The piano is better known as a solo instrument, but actually appears as part of the orchestra more frequently than you would imagine. And not just pianos – other regular keyboard instruments include harpsichord, celesta and organ. Positioned off to the back, usually near the harps and percussion, these are mostly played by just one person, proficient in the techniques needed to play most instruments.
Each of these instruments has its own distinctive sound: the celesta (‘heavenly’ in French) has a sound like little bells, the organ is as majestic and full bodied as its pipes suggest, the harpsichord’s keys pluck strings inside instead of hammer them and is mostly associated with early music, and the piano with its large range and variety of tone that can either blend or soar above the orchestra.
