The three main types of drums are:
1. Membranophones: These include drums that have a single or multiple skins called a membrane stretched over a frame or shell. They can be tuned by tightening or loosening the skin. Examples are the timpani, snare drum, bass drum, and tom-toms.
2. Idophones: These are percussion instruments that create sound by the vibration of a solid object. They are further divided into metallophones, woodophones, and skin-head instruments. Cymbals, marimbas, and vibraphones are included in this category.
3. Aerophones: These are wind instruments that produce sound by the vibration of a column of air. They include whistles, trumpets, and flutes. However, in the context of percussion, the term is sometimes used to refer to drums that use air or gas
