Rav Vast Drum is a unique instrument it's sound is close to hang drums but has more sustain more vibration in it, the construction of Rav Vast tongues is a patented  innovation, it  will allow you to play 1 main note and 3 harmonics using a flageolet. Unlike other tongue drums you can play Rav Vast as fast and expressive as you wish and the sound wont overwhelm itself as every tongue section of the drum is isolated from the other which keeps the sound clear and readable. 

It is very easy to play Rav Vast at the basic level and there is a vast space for improvement.  The sound is beautiful and mystical, easy to improvise, meditate and flow into a music dream.
