Of Aztec origin, this drum produces soothing, zen-like sounds. Like the xylophone, each metal tongue produces a unique sound. Specially designed for musical initiation, it comes with sheet music for simple, well-known tunes. To extend the pleasure of playing to that of learning, an explanatory sheet explains the relationship between the tongue drum's sounds and classical notation (C, D, E, F, G, A, B), as well as the rhythms (eighth notes, quarter notes, half notes).
