HELLO WELCOME TO THE WORLD OF MUSIC WHERE MUSIC IS CONISDERED AS GOD
WHAT ABOUT MUSIC?Music is the ‘art of combining tones in a manner to please the ear’. It may also mean sounds so combined as to make a pleasant impression on the mind.

COMPOSITION
"Composition" is the act or practice of creating a song, an instrumental music piece, a work with both singing and instruments, or another type of music. In many cultures, including Western classical music, the act of composing also includes the creation of music notation, such as a sheet music "score", which is then performed by the composer or by other singers or musicians. In popular music and traditional music, the act of composing, which is typically called songwriting, may involve the creation of a basic outline of the song, called the lead sheet, which sets out the melody, lyrics and chord progression. In classical music, the composer typically orchestrates her own compositions, but in musical theatre and in pop music, songwriters may hire an arranger to do the orchestration. In some cases, a songwriter may not use notation at all, and instead compose the song in her mind and then play or record it from memory. In jazz and popular music, notable recordings by influential performers are given the weight that written scores play in classical music.
Even when music is notated relatively precisely, as in classical music, there are many decisions that a performer has to make, because notation does not specify all of the elements of music precisely. The process of deciding how to perform music that has been previously composed and notated is termed "interpretation". Different performers' interpretations of the same work of music can vary widely, in terms of the tempos that are chosen and the playing or singing style or phrasing of the melodies. Composers and songwriters who present their own music are interpreting their songs, just as much as those who perform the music of others. The standard body of choices and techniques present at a given time and a given place is referred to as performance practice, whereas interpretation is generally used to mean the individual choices of a performer.[citation needed]
Although a musical composition often uses musical notation and has a single author, this is not always the case. A work of music can have multiple composers, which often occurs in popular music when a band collaborates to write a song, or in musical theatre, when one person writes the melodies, a second person writes the lyrics, and a third person orchestrates the songs. In some styles of music, such as the blues, a composer/songwriter may create, perform and record new songs or pieces without ever writing them down in music notation. A piece of music can also be composed with words, images, or computer programs that explain or notate how the singer or musician should create musical sounds. Examples range from avant-garde music that uses graphic notation, to text compositions such as Aus den sieben Tagen, to computer programs that select sounds for musical pieces. Music that makes heavy use of randomness and chance is called aleatoric music, and is associated with contemporary composers active in the 20th century, such as John Cage, Morton Feldman, and Witold Lutosławski. A more commonly known example of chance-based music is the sound of wind chimes jingling in a breeze.
The study of composition has traditionally been dominated by examination of methods and practice of Western classical music, but the definition of composition is broad enough the creation of popular music and traditional music songs and instrumental pieces and to include spontaneously improvised works like those of free jazz performers and African percussionists such as Ewe drummers.

NOTATION AND OTHER
In the 2000s, music notation typically means the written expression of music notes and rhythms on paper using symbols. When music is written down, the pitches and rhythm of the music, such as the notes of a melody, are notated. Music notation also often provides instructions on how to perform the music. For example, the sheet music for a song may state that the song is a "slow blues" or a "fast swing", which indicates the tempo and the genre. To read music notation, a person must have an understanding of music theory, harmony and the performance practice associated with a particular song or piece's genre.
Written notation varies with style and period of music. In the 2000s, notated music is produced as sheet music or, for individuals with computer scorewriter programs, as an image on a computer screen. In ancient times, music notation was put onto stone or clay tablets. To perform music from notation, a singer or instrumentalist requires an understanding of the rhythmic and pitch elements embodied in the symbols and the performance practice that is associated with a piece of music or a genre. In genres requiring musical improvisation, the performer often plays from music where only the chord changes and form of the song are written, requiring the performer to have a great understanding of the music's structure, harmony and the styles of a particular genre (e.g., jazz or country music).
In Western art music, the most common types of written notation are scores, which include all the music parts of an ensemble piece, and parts, which are the music notation for the individual performers or singers. In popular music, jazz, and blues, the standard musical notation is the lead sheet, which notates the melody, chords, lyrics (if it is a vocal piece), and structure of the music. Fake books are also used in jazz; they may consist of lead sheets or simply chord charts, which permit rhythm section members to improvise an accompaniment part to jazz songs. Scores and parts are also used in popular music and jazz, particularly in large ensembles such as jazz "big bands." In popular music, guitaristsand electric bass players often read music notated in tablature (often abbreviated as "tab"), which indicates the location of the notes to be played on the instrument using a diagram of the guitar or bass fingerboard. Tabulature was also used in the Baroque era to notate music for the lute, a stringed, fretted instrument.
ImprovisationMain article: Musical improvisationMusical improvisation is the creation of spontaneous music, often within (or based on) a pre-existing harmonic framework or chord progression. Improvisation is the act of instantaneous composition by performers, where compositional techniques are employed with or without preparation. Improvisation is a major part of some types of music, such as blues, jazz, and jazz fusion, in which instrumental performers improvise solos, melody lines and accompaniment parts. In the Western art music tradition, improvisation was an important skill during the Baroque era and during the Classical era. In the Baroque era, performers improvised ornaments and basso continuo keyboard players improvised chord voicings based on figured bass notation. In the Classical era, solo performers and singers improvised virtuoso cadenzas during concerts. However, in the 20th and early 21st century, as "common practice" Western art music performance became institutionalized in symphony orchestras, opera houses and ballets, improvisation has played a smaller role. At the same time, some modern composers have increasingly included improvisation in their creative work. In Indian classical music, improvisation is a core component and an essential criterion of performances.
TheoryMain article: Music theoryMusic theory encompasses the nature and mechanics of music. It often involves identifying patterns that govern composers' techniques and examining the language and notation of music. In a grand sense, music theory distills and analyzes the parameters or elements of music – rhythm, harmony (harmonic function), melody, structure, form, and texture. Broadly, music theory may include any statement, belief, or conception of or about music.[8] People who study these properties are known as music theorists. Some have applied acoustics, human physiology, and psychology to the explanation of how and why music is perceived.
ElementsMain article: Aspect of musicMusic has many different fundamentals or elements. Depending on the definition of "element" being used, these can include: pitch, beat or pulse, tempo, rhythm, melody, harmony, texture, style, allocation of voices, timbre or color, dynamics, expression, articulation, form and structure. The elements of music feature prominently in the music curriculums of Australia, UK and USA. All three curriculums identify pitch, dynamics, timbre and texture as elements, but the other identified elements of music are far from universally agreed. Below is a list of the three official versions of the "elements of music":
The phrase "the elements of music" is used in a number of different contexts. The two most common contexts can be differentiated by describing them as the "rudimentary elements of music" and the "perceptual elements of music".
Rudimentary elementsIn the 1800s, the phrase "the elements of music" and the phrase "the rudiments of music" were used interchangeably.[13][14] The elements described in these documents refer to aspects of music that are needed in order to become a musician, Recent writers such as Estrella [15] seem to be using the phrase "elements of music" in a similar manner. A definition which most accurately reflects this usage is: "the rudimentary principles of an art, science, etc.: the elements of grammar."[16] The UK's curriculum switch to the "inter-related dimensions of music" seems to be a move back to using the rudimentary elements of music.
Perceptual elementsSince the emergence of the study of psychoacoustics in the 1930s, most lists of elements of music have related more to how we hear music than how we learn to play it or study it. C.E. Seashore, in his book Psychology of Music,[17] identified four "psychological attributes of sound". These were: "pitch, loudness, time, and timbre" (p. 3). He did not call them the "elements of music" but referred to them as "elemental components" (p. 2). Nonetheless these elemental components link precisely with four of the most common musical elements: "Pitch" and "timbre" match exactly, "loudness" links with dynamics and "time" links with the time-based elements of rhythm, duration and tempo. This usage of the phrase "the elements of music" links more closely with Webster's New 20th Century Dictionary definition of an element as: "a substance which cannot be divided into a simpler form by known methods"[18] and educational institutions' lists of elements align with this list as well.
Writers of lists of "rudimentary elements of music" vary their lists depending on their personal priorities. However, in relation to the perceptual elements of music, it should be possible to identify a list of discrete elements which can be independently manipulated to achieve an intended musical effect. It seems at this stage that there is still research to be done in this area.
Analysis of styles
Funk places most of its emphasis on rhythm and groove, with entire songs based around a vamp on a single chord. Pictured are the influential funk musicians George Clinton and Parliament Funkadelic in 2006.Some styles of music place an emphasis on certain of these fundamentals, while others place less emphasis on certain elements. To give one example, while Bebop-era jazz makes use of very complex chords, including altered dominants and challenging chord progressions, with chords changing two or more times per bar and keys changing several times in a tune, funk places most of its emphasis on rhythm and groove, with entire songs based around a vamp on a single chord. While Romantic era classical music from the mid- to late-1800s makes great use of dramatic changes of dynamics, from whispering pianissimo sections to thunderous fortissimo sections, some entire Baroque dance suites for harpsichord from the early 1700s may use a single dynamic. To give another example, while some art music pieces, such as symphonies are very long, some pop songs are just a few minutes long.

ELEMENTS OF MUSIC
PITCH AND MELODY
Pitch is an aspect of a sound that we can hear, reflecting whether one musical sound, note or tone is "higher" or "lower" than another musical sound, note or tone. We can talk about the highness or lowness of pitch in the more general sense, such as the way a listener hears a piercingly high piccolo note or whistling tone as higher in pitch than a deep thump of a bass drum. We also talk about pitch in the precise sense associated with musical melodies, basslines and chords. Precise pitch can only be determined in sounds that have a frequency that is clear and stable enough to distinguish from noise. For example, it is much easier for listeners to discern the pitch of a single note played on a piano than to try to discern the pitch of a crash cymbal that is struck.
A melody (also called a "tune") is a series of pitches (notes) sounding in succession (one after the other), often in a rising and falling pattern. The notes of a melody are typically created using pitch systems such as scales or modes. Melodies also often contain notes from the chords used in the song. The melodies in simple folk songs and traditional songs may use only the notes of a single scale, the scale associated with the tonic note or key of a given song. For example, a folk song in the key of C (also referred to as C major) may have a melody that uses only the notes of the C major scale (the individual notes C, D, E, F, G, A, B and C; these are the "white notes" on a piano keyboard. On the other hand, Bebop-era jazz from the 1940s and contemporary music from the 20th and 21st centuries may use melodies with many chromatic notes (i.e., notes in addition to the notes of the major scale; on a piano, a chromatic scale would include all the notes on the keyboard, including the "white notes" and "black notes" and unusual scales, such as the whole tone scale (a whole tone scale in the key of C would contain the notes C, D, E, F♯, G♯ and A♯). A low, deep musical line played by bass instruments such as double bass,

A low, deep musical line played by bass instruments such as double bass,
HARMONY AND CHORDS
When musicians play three or more different notes at the same time, this creates a chord. In Western music, including classical music, pop music, rock music and many related styles, the most common chords are triads– three notes usually played at the same time. The most commonly used chords are the major chord and the minor chord. An example of a major chord is the three pitches C, E and G. An example of a minor chord is the three pitches A, C and E. (Pictured is a guitar playerperforming a chord on a guitar).
Harmony refers to the "vertical" sounds of pitches in music, which means pitches that are played or sung together at the same time to create a chord. Usually this means the notes are played at the same time, although harmony may also be implied by a melody that outlines a harmonic structure (i.e., by using melody notes that are played one after the other, outlining the notes of a chord). In music written using the system of major-minor tonality ("keys"), which includes most classical music written from 1600 to 1900 and most Western pop, rock and traditional music, the key of a piece determines the scale used, which centres around the "home note" or tonic of the key. Simple classical pieces and many pop and traditional music songs are written so that all the music is in a single key. More complex Classical, pop and traditional music songs and pieces may have two keys (and in some cases three or more keys). Classical music from the Romantic era (written from about 1820–1900) often contains multiple keys, as does jazz, especially Bebop jazz from the 1940s, in which the key or "home note" of a song may change every four bars or even every two bars.
RHYTHM
Rhythm is the arrangement of sounds and silences in time. Meter animates time in regular pulse groupings, called measures or bars, which in Western classical, popular and traditional music often group notes in sets of two (e.g., 2/4 time), three (e.g., 3/4 time, also known as Waltz time, or 3/8 time), or four (e.g., 4/4 time). Meters are made easier to hear because songs and pieces often (but not always) place an emphasis on the first beat of each grouping. Notable exceptions exist, such as the backbeat used in much Western pop and rock, in which a song that uses a measure that consists of four beats (called 4/4 time or common time) will have accents on beats two and four, which are typically performed by the drummer on the snare drum, a loud and distinctive-sounding percussion instrument. In pop and rock, the rhythm parts of a song are played by the rhythm section, which includes chord-playing instruments (e.g., electric guitar, acoustic guitar, piano, or other keyboard instruments), a bass instrument (typically electric bass or for some styles such as jazz and bluegrass, double bass) and a drum kit player.
TEXTURE
Musical texture is the overall sound of a piece of music or song. The texture of a piece or sing is determined by how the melodic, rhythmic, and harmonic materials are combined in a composition, thus determining the overall nature of the sound in a piece. Texture is often described in regard to the density, or thickness, and range, or width, between lowest and highest pitches, in relative terms as well as more specifically distinguished according to the number of voices, or parts, and the relationship between these voices (see common types below). For example, a thick texture contains many 'layers' of instruments. One of these layers could be a string section, or another brass. The thickness also is affected by the amount and the richness of the instruments. Texture is commonly described according to the number of and relationship between parts or lines of music:
- monophony: a single melody (or "tune") with neither instrumental accompaniment nor a harmony part. A mother singing a lullaby to her baby would be an example.
- heterophony: two or more instruments or singers playing/singing the same melody, but with each performer slightly varying the rhythm or speed of the melody or adding different ornaments to the melody. Two bluegrass fiddlers playing the same traditional fiddle tune together will typically each vary the melody a bit and each add different ornaments.
- polyphony: multiple independent melody lines that interweave together, which are sung or played at the same time. Choral music written in the Renaissance music era was typically written in this style. A round, which is a song such as "Row, Row, Row Your Boat", which different groups of singers all start to sing at a different time, is a simple example of polyphony.
- homophony: a clear melody supported by chordal accompaniment. Most Western popular music songs from the 19th century onward are written in this texture.
TIMBRE
Timbre, sometimes called "color" or "tone color" is the quality or sound of a voice or instrument.[19] Timbre is what makes a particular musical sound different from another, even when they have the same pitch and loudness. For example, a 440 Hz A note sounds different when it is played on oboe, piano, violin or electric guitar. Even if different players of the same instrument play the same note, their notes might sound different due to differences in instrumental technique (e.g., different embouchures), different types of accessories (e.g., mouthpieces for brass players, reeds for oboe and bassoon players) or strings made out of different materials for string players (e.g., gut strings versus steel strings). Even two instrumentalists playing the same note on the same instrument (one after the other) may sound different due to different ways of playing the instrument (e.g., two string players might hold the bow differently).
The physical characteristics of sound that determine the perception of timbre include the spectrum, envelope and overtones of a note or musical sound. For electric instruments developed in the 20th century, such as electric guitar, electric bass and electric piano, the performer can also change the tone by adjusting equalizer controls, tone controls on the instrument, and by using electronic effects units such as distortion pedals. The tone of the electric Hammond organ is controlled by adjusting drawbars.

The tone of the electric Hammond organ is controlled by adjusting drawbars.
EXPRESSION
Singers add expression to the melodies they sing using many methods, including changing the tone of their singing, adding vibrato to certain notes, or emphasizing important words in the lyrics.
Expressive qualities are those elements in music that create change in music without changing the main pitches or substantially changing the rhythms of the melody and its accompaniment. Performers, including singers and instrumentalists, can add musical expression to a song or piece by adding phrasing, by adding effects such as vibrato (with voice and some instruments, such as guitar, violin, brass instruments and woodwinds), dynamics (the loudness or softness of piece or a section of it), tempo fluctuations (e.g., ritardando or accelerando, which are, respectively slowing down and speeding up the tempo), by adding pauses or fermatas on a cadence, and by changing the articulation of the notes (e.g., making notes more pronounced or accented, by making notes more legato, which means smoothly connected, or by making notes shorter).
FORM
In music, form describes how the overall structure or plan of a song or piece of music,[20] and it describes the layout of a composition as divided into sections.[21] In the early 20th century, Tin Pan Alley songs and Broadway musical songs were often in AABA 32 bar form, in which the A sections repeated the same eight bar melody and the B section provided a contrasting melody and/or harmony for 8 bars. From the 1960s onward, Western pop and rock songs are often in verse-chorus form, which is based around a sequence of verse and chorus ("refrain") sections, with new lyrics for most verses and repeating lyrics for the choruses. Popular music often makes use of strophic form, sometimes in conjunction with the twelve bar blues.[citation needed]
In the tenth edition of The Oxford Companion to Music, Percy Scholes defines musical form as "a series of strategies designed to find a successful mean between the opposite extremes of unrelieved repetition and unrelieved alteration."[22] Examples of common forms of Western music include the fugue, the invention, sonata-allegro, canon, strophic, theme and variations, and rondo. Scholes states that European classical music had only six stand-alone forms: simple binary, simple ternary, compound binary, rondo, air with variations, and fugue (although musicologist Alfred Mann emphasized that the fugue is primarily a method of composition that has sometimes taken on certain structural conventions.[23])
Where a piece cannot readily be broken down into sectional units (though it might borrow some form from a poem, story or programme), it is said to be through-composed. Such is often the case with a fantasia, prelude, rhapsody, etude (or study), symphonic poem, Bagatelle, impromptu, etc.[citation needed] Professor Charles Keil classified forms and formal detail as "sectional, developmental, or variational."[24]
Sectional formThis form is built from a sequence of clear-cut units[25] that may be referred to by letters but also often have generic names such as introduction and coda, exposition, development and recapitulation, verse, chorus or refrain, and bridge. Introductions and codas, when they are no more than that, are frequently excluded from formal analysis. All such units may typically be eight measures long. Sectional forms include:
Strophic formThis form is defined by its "unrelieved repetition" (AAAA...).
MedleyMedley, potpourri is the extreme opposite, that of "unrelieved variation": it is simply an indefinite sequence of self-contained sections (ABCD...), sometimes with repeats (AABBCCDD...). Examples include orchestral overtures, which are sometimes no more than a string of the best tunes of the musical theatre show or opera to come.
Binary form
Binary form in major and minor keys. Each section must be at least three phrases long.[26]This form uses two sections (AB...), each often repeated (AABB...). In 18th-century Western classical music, "simple binary" form was often used for dances and carried with it the convention that the two sections should be in different musical keys but same rhythm, duration and tone. The alternation of two tunes gives enough variety to permit a dance to be extended for as long as desired.
Ternary formThis form has three parts. In Western classical music a simple ternary form has a third section that is a recapitulation of the first (ABA). Often, the first section is repeated (AABA). This approach was popular in the 18th-century operatic aria,[citation needed] and was called da capo (i.e. "repeat from the top") form. Later, it gave rise to the 32-bar song, with the B section then often referred to as the "middle eight". A song has more need than a dance of a self-contained form with a beginning and an end of course.
Rondo formThis form has a recurring theme alternating with different (usually contrasting) sections called "episodes". It may be asymmetrical (ABACADAEA) or symmetrical (ABACABA). A recurring section, especially the main theme, is sometimes more thoroughly varied, or else one episode may be a "development" of it. A similar arrangement is the ritornello form of the Baroque concerto grosso. Arch form (ABCBA) resembles a symmetrical rondo without intermediate repetitions of the main theme. It is normally used in a round.
Variational formVariational forms are those in which variation is an important formative element.
Theme and Variations: a theme, which in itself can be of any shorter form (binary, ternary, etc.), forms the only "section" and is repeated indefinitely (as in strophic form) but is varied each time (A,B,A,F,Z,A), so as to make a sort of sectional chain form. An important variant of this, much used in 17th-century British music and in the Passacaglia and Chaconne, was that of the ground bass - a repeating bass theme or basso ostinato over and around which the rest of the structure unfolds, often, but not always, spinning polyphonicor contrapuntal threads, or improvising divisions and descants. This is said by Scholes (1977) to be the form par excellence of unaccompanied or accompanied solo instrumental music. The Rondo is often found with sections varied (AA1BA2CA3BA4) or (ABA1CA2B1A).
Developmental formDevelopmental forms are built directly from smaller units, such as motifs. A well-known Classical piece with a motif is Beethoven's fifth symphony, which starts with three short repeated notes and then a long note. In Classical pieces that are based on motifs, the motif is usually combined, varied and worked out in different ways, perhaps having a symmetrical or arch-like underpinning and a progressive development from beginning to end. By far the most important developmental form in Western classical music is Sonata form. This form, also known as sonata form, first movement form, compound binary, ternary and a variety of other names,[example needed] developed from the binary-formed dance movement described above but is almost always cast in a greater ternary form having the nominal subdivisions of Exposition, Development and Recapitulation. Usually, but not always, the "A" parts (Exposition and Recapitulation, respectively) may be subdivided into two or three themes or theme groups which are taken asunder and recombined to form the "B" part (the development) - thus e. g.. This developmental form is generally confined to certain sections of the piece, as to the middle section of the first movement of a sonata, though 19th-century composers such as Berlioz, Liszt and Wagner made valiant efforts to derive large-scale works purely or mainly from the motif.
In the tenth edition of The Oxford Companion to Music, Percy Scholes defines musical form as "a series of strategies designed to find a successful mean between the opposite extremes of unrelieved repetition and unrelieved alteration."[22] Examples of common forms of Western music include the fugue, the invention, sonata-allegro, canon, strophic, theme and variations, and rondo. Scholes states that European classical music had only six stand-alone forms: simple binary, simple ternary, compound binary, rondo, air with variations, and fugue (although musicologist Alfred Mann emphasized that the fugue is primarily a method of composition that has sometimes taken on certain structural conventions.[23])
Where a piece cannot readily be broken down into sectional units (though it might borrow some form from a poem, story or programme), it is said to be through-composed. Such is often the case with a fantasia, prelude, rhapsody, etude (or study), symphonic poem, Bagatelle, impromptu, etc.[citation needed] Professor Charles Keil classified forms and formal detail as "sectional, developmental, or variational."[24]
Sectional formThis form is built from a sequence of clear-cut units[25] that may be referred to by letters but also often have generic names such as introduction and coda, exposition, development and recapitulation, verse, chorus or refrain, and bridge. Introductions and codas, when they are no more than that, are frequently excluded from formal analysis. All such units may typically be eight measures long. Sectional forms include:
Strophic formThis form is defined by its "unrelieved repetition" (AAAA...).
MedleyMedley, potpourri is the extreme opposite, that of "unrelieved variation": it is simply an indefinite sequence of self-contained sections (ABCD...), sometimes with repeats (AABBCCDD...). Examples include orchestral overtures, which are sometimes no more than a string of the best tunes of the musical theatre show or opera to come.
Binary form
Binary form in major and minor keys. Each section must be at least three phrases long.[26]This form uses two sections (AB...), each often repeated (AABB...). In 18th-century Western classical music, "simple binary" form was often used for dances and carried with it the convention that the two sections should be in different musical keys but same rhythm, duration and tone. The alternation of two tunes gives enough variety to permit a dance to be extended for as long as desired.
Ternary formThis form has three parts. In Western classical music a simple ternary form has a third section that is a recapitulation of the first (ABA). Often, the first section is repeated (AABA). This approach was popular in the 18th-century operatic aria,[citation needed] and was called da capo (i.e. "repeat from the top") form. Later, it gave rise to the 32-bar song, with the B section then often referred to as the "middle eight". A song has more need than a dance of a self-contained form with a beginning and an end of course.
