Context_2 : Phoebe Snow (born Phoebe Ann Laub; July 17, 1950 April 26, 2011) was an American singer, songwriter, and guitarist, best known for her 1975 song "Poetry Man".

Context_3 : Naka Rabemanantsoa is a pianist and composer of "vakondrazana" and "ba-gasy" music from the central highlands of Madagascar. He was a major composer for the Malagasy theatrical genre that reached its peak between 1920 and 1940 at the Theatre d'Isotry in Antananarivo. His pieces were typically written for piano, and although his pieces were often adapted for solo, duet or choral vocal accompaniment sung in the Malagasy language, he was a strong proponent of preserving strictly instrumental accompaniment for theatrical performances. His songs form part of the canon of classical Malagasy piano music, and a street in downtown Antananarivo is named after him.

Context_8 : Accompaniment is the musical parts which provide 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 (chords and a bassline are easier to play simultaneously on keyboard instruments, but a fingerpicking guitarist can play chords and a bassline simultaneously on guitar). 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 (e.g., Bobby McFerrin).
