- Tabla (an hour-glass shaped drum)
- Daff (a frame drum)
Here they are performed in a religious ritual called hadra. Name the instruments you see.

Classification of musical instruments by vibration dimension and material
- Idiophones: the whole instrument vibrates (3D)
- Membranophones: a membrane vibrates (2D)
- Chordophones: a string vibrates (1D)
- Aerophones: an air column vibrates (1D)
