Cello
The cellos are a critical part of orchestral music; all symphonic works
involve the cello section, and many pieces require cello soli or solos.
Much of the time, cellos provide part of the low-register harmony for
the orchestra. Often, the cello section plays the melody for a brief
period, before returning to the harmony role. There are also cello
concertos, which are orchestral pieces that feature a solo cellist
accompanied by an entire orchestra.
