Are the notes on piano only ones possible?

The notes on a piano are not the only ones possible. There are many other musical notes that can be played on different instruments. For example, the violin can play notes that are higher than the highest note on a piano, and the cello can play notes that are lower than the lowest note on a piano. There are also many other instruments that can play notes that are not possible on a piano, such as the flute, clarinet, trumpet, and trombone.
