Explain the parts of the instrument. For a piano, this would include the keys, hammers, strings, and the soundboard.
A brief section on where it came from (e.g., the Piano evolved from the Harpsichord in the early 1700s).
List the different versions of that specific instrument:
Grand Piano: Horizontal strings, used for concerts.
Upright Piano: Vertical strings, better for homes/studios.
How is it used? Is it a lead instrument, rhythm, or both?
