Classification of musical instruments by vibration dimension and material

Hornbostel-Sachs

• Idiophones: the whole instrument vibrates (3D)
• Membranophones: a membrane vibrates (2D)
• Chordophones: a string vibrates (1D)
• Aerophones: an air column vibrates (1D)

Animations:

• Idiophone: tuning fork
• Membranophone
• Chordophone
• Aerophone: open flute
