Solution
Musical instruments are of three main categories:
Stringed instruments
Percussion or membrane instruments
Wind instruments
Percussion or Membrane Instruments :
Drums, tablas, and tambourines use a stretched flexible membrane over a hollow wooden frame.
When the membrane is struck, a series of waves is set into vibrations, which in turn carry the vibrations to the air column in the soundbox, producing the musical sound of varying frequencies.
Most percussion instruments do not have a definite pitch and are used for rhythm and impact.
