Drums are the world's oldest and most widespread
musical instruments, and the basic design has remained virtually
unchanged for thousands of years.
Drums may be played individually, with the player using a single drum,
and some drums such as the djembe are almost always played in
this way.
Others are normally played in a set of two or more, all played by the
one player, such as bongo drums and timpani.
A number of different drums together with cymbals form the basic modern
drum kit.
