Accompaniment


Accompaniment is the musical part which provides the rhythmic and/or harmonic support for the melody or main themes of a song or instrumental piece. There are many different styles and types of accompaniment in different genres and styles of music. In homophonic music, the main accompaniment approach used in popular music, a clear vocal melody is supported by subordinate chords. In popular music and traditional music, the accompaniment parts typically provide the "beat" for the music and outline the chord progression of the song or instrumental piece.
The accompaniment for a vocal melody or instrumental solo can be played by a single musician playing an instrument such as piano, pipe organ, or guitar. While any instrument can in theory be used as an accompaniment instrument, keyboard and guitar-family instruments tend to be used if there is only a single instrument, as these instruments can play chords and basslines simultaneously. A solo singer can accompany herself by playing guitar or piano while she sings, and in some rare cases, a solo singer can even accompany himself or herself just using his or her voice and body.
Alternatively, the accompaniment to a vocal melody or instrumental solo can be provided by a musical ensemble, ranging in size from a duo ; a trio ; a quartet ; all the way to larger ensembles, such as concert bands, Big Bands, pit orchestras in musical theatre; and orchestras, which, in addition to playing symphonies, can also provide accompaniment to a concerto solo instrumentalist or to solo singers in opera. With choral music, the accompaniment to a vocal solo can be provided by other singers in the choir, who sing harmony parts or countermelodies.
Accompaniment parts range from so simple that a beginner can play them to so complex that only an advanced player or singer can perform them.

Definition

An accompanist is a musician who plays an accompaniment part. Accompanists often play keyboard instruments or, in folk music and traditional styles, a guitar. While sight-reading is important for many types of musicians, it is essential for professional accompanists. In auditions for musical theater and orchestras, an accompanist will often have to sight read music.
A number of classical pianists have found success as accompanists rather than soloists; arguably the best known example is Gerald Moore, well known as a Lieder accompanist. In some American schools, the term collaborative piano is used, and hence, the title "collaborative pianist" is replacing the title accompanist, because in many art songs and contemporary classical music songs, the piano part is complex and demands an advanced level of musicianship and technique. The term accompanist also refers to a musician who plays for singers, dancers, and other performers at an audition or rehearsal—but who does not necessarily participate in the ensemble that plays for the final performance.

Accompaniment figure

An accompaniment figure is a musical gesture used repeatedly in an accompaniment, such as:
Notated accompaniment may be indicated obbligato or ad libitum.

Dialogue accompaniment

Dialogue accompaniment is a form of call and response in which the lead and accompaniment alternate, the accompaniment playing during the rests of the lead and providing a drone or silence during the main melody or vocal.

Notation and improvisation

The accompaniment instrumentalists and/or singers can be provided with a fully notated accompaniment part written or printed on sheet music. This is the norm in Classical music and in most large ensemble writing. In popular music and traditional music, the accompaniment instrumentalists often improvise their accompaniment, either based on a lead sheet or chord chart which indicates the chords used in the song or piece or by "playing by ear". To achieve a stylistic correct sound the accompaniment pattern should remind or imitate the original version using similar .
Chord-playing musicians can improvise chords, "fill-in" melodic lines and solos from the chord chart. It is rare for chords to be fully written out in music notation in pop and traditional music. Some guitarists, bassists and other stringed instrumentalists read accompaniment parts using tabulature, a notation system which shows the musician where on the instrument to play the notes. Drummers can play accompaniment by following the lead sheet, a sheet music part in music notation, or by playing by ear.
In pop and traditional music, bass players, which may be upright bass or electric bass, or another instrument, such as bass synth, depending on the style of music, are usually expected to be able to improvise a bassline from a chord chart or learn the song from a recording. In some cases, an arranger or composer may give a bassist a bass part that is fully written out in music notation. In. some arranged music parts, there is a mix of written-out accompaniment and improvisation. For example, in a big band bass part, the introduction and melody to a tune may have a fully notated bassline, but then for the improvised solos, the arranger may just write out chord symbols, with the expectation that the bassist improvise her own walking bass part.
