Polyphony is a musical texture in which two or more independent melodic lines are performed at the same time. It is one of the principal forms of musical texture in Western music.
What is polyphony?
In polyphonic music, each voice has its own melodic identity while combining with the other voices to create harmony. This differs from homophony, where one main melody is supported by accompanying chords.
Polyphony is especially associated with composers such as J.S. Bach, but it also appears in jazz, contemporary music and many keyboard styles.
How is polyphony used in piano playing?
The piano is ideally suited to polyphonic playing because both hands can perform independent musical lines at the same time. Developing this skill improves hand independence, musical coordination and expressive control.
Understanding polyphony also helps pianists interpret contrapuntal music and create richer musical textures.
