Musical composition for any instrumen music

Musical composition can refer to an original piece of music, the structure of a musical piece, or the process of creating a new piece of music. People who practice composition are called composers.

A piece of music exists in the form of a composition in musical notation or as a single acoustic event (a live performance or recorded track). If composed before being performed, music can be performed from memory, through written musical notation, or through a combination of both. Compositions comprise musical elements, which vary widely from person to person and between cultures. Improvisation is the act of composing during the performance, assembling musical elements spontaneously.

Piece is a, "general, non-technical term [that began to be] applied mainly to instrumental compositions from the 17th century onwards....other than when they are taken individually 'piece' and its equivalents are rarely used of movements in sonatas or symphonies....composers have used all these terms [in their different languages] frequently in compound forms [e.g. Klavierstück]....In vocal music...the term is most frequently used for operatic ensembles.....etc.

Important in tonal musical composition is the scale for the notes used, including the mode and tonic note. In music using twelve tone techniques, the tone row is even more comprehensive a factor than a scale. Similarly, music of the Middle East employs compositions that are rigidly based on a specific mode (maqam) often within improvisational contexts, as does Indian classical music in both the Hindustani and the Carnatic systems, gamelans of Java and Bali, and much music in Africa.

People who practice composition are called composers. Compositional techniques are the methods used to create music. Useful skills in composition include writing musical notation, music theory, instrumentation, and handling musical ensembles (orchestration). Other skills include extended techniques such as improvisation, musical montage, preparing instruments, using non-traditional instruments, and other methods of sound production.

Methods

One method to compose music is starting with a base series of chords. These chords could be selected arbitrarily or with specific purpose to reflect the tone of the emotion being conveyed. For example, selecting a minor key, but with mostly major chords (i.e. III, VI, VII) might convey a hopeful feeling. Once the series of chords is selected, additional lines are added to embellish, adding depth to the music. Usually this includes at least a lead melody line and often one or more harmony lines. Popular music is often written this way (see: Song structure (popular music)) where a selected series of chords forms the structure of each of a particular section of the song (ex. Verse, Chorus). The melody line is often dependent on the writer's chosen lyrics and can vary in detail from verse to verse.

Another method involves free playing of your desired instrument. For example, a pianist might simply sit and start playing chords, melodies, or random notes that come to mind in order to find some inspiration, then build on the discovered lines to add depth.

As technology progresses, new and inventive methods of music composition come about. One such method involves using computer algorithms to directly translate the phonetics of speech into digital sound.

Structure

Composers may decide to divide their music into sections. In classical music, one common form of songwriting is Sonata form. This form involves an Exposition, Development, and Recapitulation. The end speaks to the beginning, concluding things, while the development allows for deviations from the norm of the exposition. Many contemporary songs are organized into sections as well. These sections are usually alternating verse and chorus, often with a bridge before the last chorus. The differing verses will share chord progressions while the chorus is often exactly the same throughout.

 

The task of adapting a composition for musical instruments/ensembles, called arranging or orchestrating, may be undertaken by the composer or separately by an arranger based on the composer's core composition. A composition may have multiple arrangements based on such factors as intended audience type and breadth, musical genre or stylistic treatment, recorded or live performance considerations, available musicians and instruments, commercial goals and economic constraints. Based on such factors, composers or arrangers must decide upon the instrumentation of the original work. Today, the contemporary composer can virtually write for almost any combination of instruments. Some common group settings include music for Full Orchestra (consisting of just about every instrument group), Wind Ensemble (or Concert Band, which consists of larger sections and greater diversity of wind, brass and percussion instruments than are usually found in the orchestra), or a chamber group (a small number of instruments, but at least two). The composer may also choose to write for only one instrument, in which case this is called a solo.

Composers are not limited to writing only for instruments, they may also decide to write for voice (including choral works, operas, and musicals) or percussion instruments or electronic instruments. Alternatively, as is the case with musique concrète, the composer can work with many sounds often not associated with the creation of music, such as typewriters, sirens, and so forth. 

In Elizabeth Swados' Listening Out Loud, she explains how a composer must know the full capabilities of each instrument and how they must complement each other, not compete. She gives an example of how in an earlier composition of hers, she had the tuba above the piccolo. This would clearly drown the piccolo out, thus giving it no purpose in the composition. Each instrument chosen to be in a piece must have a reason for being there that adds to what the composer is trying to convey within the work

Arranging is composition which employs prior material so as to comment upon it such as in mash-ups and various contemporary classical works. The process first requires analysis of existing music, and then rewriting (and often transcription) for an instrumentation other than that for which it was originally intended. It often (but not always) involves new supporting material injected by the arranger. Different versions of a composed piece of music is referred to as an arrangement.

Musical form

The term musical form (or musical architecture) refers to the overall structure or plan of a piece of music,^[1] and it describes the layout of a composition as divided into sections.^[2] 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."^[3]

Musicologist Richard Middleton describes form through repetition and difference: difference is the distance moved from a repeat; a repeat being the smallest difference. Difference is quantitative and qualitative; how far different and what type of difference. According to Middleton, musical form is "the shape or structure of the work." In many cases, form depends on statement and restatement, unity and variety, contrast and connection.

 

Composer

Louis-Nicolas Clerambault

A composer (Latin com+ponere, literally "one who puts together") is a person who creates music, either by musical notation or oral tradition, for interpretation and performance, or through direct manipulation of sonic material through electronic media. The level of distinction between composers and other musicians varies, which affects issues such as copyright and the deference given to individual interpretations of a particular piece of music.^{[citation needed]} In the development of European music, the function of composing music initially did not have much greater importance than that of performing it. The preservation of individual compositions did not receive enormous attention and musicians generally had no qualms about modifying compositions for performance. Over time, however, the written notation of the composer came to be treated as strict instructions from which performers should not deviate without good practical or artistic reason. Performers do, however, play the music and interpret it in a way that is all their own. In fact, in the concerto form, the soloist would often compose and perform a cadenza as a way to express their individual interpretation of the piece.

In as much as the role of the composer in western art music has seen continued solidification, in alternative idioms (i.e. jazz, experimental music) it has in some ways become increasingly complex or vague. For instance, in certain contexts - the line between composer and performer, sound designer, arranger, producer, and other roles - can be quite blurred.

The term "composer" is often used to refer to composers of instrumental music, such as those found in classical, jazz or other forms of art and traditional music. In popular and folk music, the composer is usually called a songwriter, since the music generally takes the form of a song. Since the mid-20th century, the term has expanded to accommodate creators of electroacoustic music, in which composers directly create sonic material in any of the various electronic media. This is distinct from instrumental composition, where the work is represented by a musical score to be interpreted by performers.

Famous composers have tended to cluster in certain cities throughout history. Based on over 12,000 prominent composers listed in Grove Music Online and using word count measurement techniques the most important cities for classical music can be quantitatively identified.
Paris has been the main hub for classical music of all times. It was ranked fifth in the 15th and 16th centuries but first in the 17th to 20th centuries inclusive. London was the second most meaningful city: eight in the 15th century, seventh in the 16th, fifth in the 17th, second in the 18th and 19th centuries, and fourth in the 20th century. Rome topped the rankings in the 15th century, dropped to second in the 16th and 17th centuries, eight in the 18th century, ninth in the 19th century but back at sixth in the 20th century. Berlin appears in the top ten ranking only in the 18th century, and was ranked third most important city in both the 19th and 20th centuries. New York entered the rankings in the 19th century (at fifth place) and stood at second rank in the 20th century.
