Comping (jazz) in the context of "Solo (music)"

A chord chart (or chart) is a form of musical notation that describes the basic harmonic and rhythmic information for a song or tune. It is the most common form of notation used by professional session musicians playing jazz or popular music. It is intended primarily for a rhythm section (usually consisting of piano, guitar, drums and bass). In these genres the musicians are expected to be able to improvise the individual notes used for the chords (the "voicing") and the appropriate ornamentation, counter melody or bassline.

In some chord charts, the harmony is given as a series of chord symbols above a traditional musical staff. The rhythmic information can be very specific and written using a form of traditional notation, sometimes called rhythmic notation, or it can be completely unspecified using slash notation, allowing the musician to fill the bar with chords or fills any way they see fit (called comping). In Nashville notation the key is left unspecified on the chart by substituting numbers for chord names. This facilitates on-the-spot key changes to songs. Chord charts may also include explicit parts written in modern music notation (such as a musical riff that the song is dependent on for character), lyrics or lyric fragments, and various other information to help the musician compose and play their part.

A rhythm section is a group of musicians within a music ensemble or band that provides the underlying rhythm, harmony and pulse of the accompaniment, providing a rhythmic and harmonic reference and "beat" for the rest of the band.The rhythm section is often contrasted with the roles of other musicians in the band, such as the lead guitarist or lead vocals whose primary job is to carry the melody.

The core elements of the rhythm section are usually the drum kit and bass. The drums and bass provide the basic pulse and groove of a song.The section is augmented by other instruments such as keyboard instruments and guitars that are used to play the chord progression upon which the song is based.The bass instrument (either double bass, or electric bass guitar, or another low-register instrument such as the synth bass, depending on the group and its style of music) plays the low-pitched bassline. The bassline is a musical part that supports the chord progression, typically by playing a musically interesting bassline that outlines the important notes of the harmony, often by emphasizing the root, fifth, and third of each chord.

"The Charleston" is a jazz composition that was written to accompany the Charleston dance. It was composed in 1923, with lyrics by Cecil Mack and music by James P. Johnson, a composer and early leader of the stride piano school of jazz piano.

The song was featured in the American black Broadway musical comedy show Runnin' Wild, which had its premiere at the New Colonial Theatre in New York on October 29, 1923. The music of the dockworkers from South Carolina inspired Johnson to compose the music. The dance known as the Charleston came to characterize the times. Lyrics, though rarely sung (an exception is Chubby Checker's 1961 recording), were penned by Cecil Mack, himself one of the most accomplished songwriters of the early 1900s. The song's driving rhythm, basically the first bar of a 3 2 clave, came to have widespread use in jazz comping and musicians still reference it by name. Harmonically, the song features a five-chord ragtime progression (I-III7-VI7-II7-V7-I).
