DiscoverE
Some instruments of Egypt
- Kawala (a short end-blown reed flute, open on both ends)
- Nay (like a kawala, but longer)
- Toora (cymbals, beaten together)
- Oud (fretless lute)
- 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.
Which instrument didn't appear?
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)
Animations:
Virtual instrument museum, organized according to Hornbostel-Sachs
Slow motion videos:
How would you classify the Egyptian instruments?
- Kawala
- Nay
- Toora
- Oud
