The piano is a crucial instrument in many Western musical genres. Pianos are used in soloing or melodic roles and as accompaniment instruments. Pianos can be played alone, with a voice or other instrument, in small groups (bands and chamber music ensembles) and large ensembles (big band or orchestra). A large number of composers and songwriters are proficient pianists because the piano keyboard offers an effective means of experimenting with complex melodic and harmonic interplay of chords and trying out multiple, independent melody lines that are played at the same time. Pianos are used by composers doing film and television scoring, as the large range permits composers to try out melodies and bass lines, even if the music will be orchestrated for other instruments.
