The terms 'gong' and 'tam-tam' are often used interchangeably. Technically, gongs have an identifiable pitch while tam-tams are indefinite-pitched instruments having a wider spectrum of overtones.

A gong with a raised 'boss' in its center is often called a button gong, and such instruments are prominent in Javanese gamelan orchestras.
