The piano, bass and drums make up the rhythm section; their main function is to accompany and support trumpet players and others; they can also improvise on their own. The pianist's main job is to play chords (the music that accompanies the melodies) in a lively and rhythmic way. The core of the rhythm section is composed of the piano, guitar, bass and drums, and the heart of the rhythm section is the bass and drums. Together they set the tone of the song by setting the basic pulse and the basic feel or rhythm, and their parts almost always complement each other.
So start there and test just these two players. Then, continue adding your compilation instruments one at a time until you hear the entire section. The piano is unique among most musical instruments, since it can play melody and harmony simultaneously, which makes it capable of playing an accompanying or leading role. In that sense, you can think of him as the ideal member of the ensemble, one of the main reasons why jazz composers and orchestra conductors have relied on this instrument for a long time.
As a solo artist and with his group Return To Forever, Corea adopted both traditional piano and modern keyboard instruments, such as synthesizers, skillfully blending elements of Latin music with sounds oriented to rock and funk, giving new life to jazz and presenting it to a worldwide audience of millions of people. More than a century old and counting, the jazz piano continues to push the limits, maintaining a long tradition of musical innovation and bold exploration. Although primarily regarded as a prolific and influential composer, Ellington was also a talented pianist, and his scant style of compiling to support the soloist greatly contributed to promoting the role of the piano in modern jazz.
