Coin Tongue Drum (Double sided)

Coin is an inique double sided tongue drum instrument. What makes it unique? First of all, it is made of solid brass and aluminum. Both metals are stainless and have very musicals sound. Brass has warm and deep sound, aluminum is bright and loud. Also, Coin drum has both sides tuned. And since the material of each side is different, it has 2 completely different tones each side - warm and low on brass and crispy and loud on the aluminum side. Also, another one essential feature - the instrument is very compact, just 14" (35 cm) diameter and has very wide range of notes for such a compact drum. But the most essential featur of a Coin model is that it is more than just 2 scales and 2 differnt sounds in 1 instrument - combining both sides we got an origianl coin sound which could be in few words calles as "natural reverb" or maybe "chorus" effect - when you play one side, you can hear the sound of the second side so the overtones are huge and sustain is very long https://www.youtube.co
