New sound model of RAV VAST2: B Universal (RUS) (B) D F# A C# D E F# A
This is a truly revolutionary instrument in a family of metal tuned
percussion. Due to special patented technology there's up to 6 harmonics tuned on each tongue. On a central note of drum there's 7 harmonics tuned. It's possible to separate those harmonics and extend the range of the instrument to full 2 octaves of the scale. Imagine 8 bells tuned to the scale and on each of them all the partials are tuned as well! That's how we would describe the sound of this instrument.
The instrument is developed and being made by Andrej Remjannikov.
It's fine tuned instrument which can be played by beginners and by
professional musicians. It can be used for the stage performances,
studio recordings and for healing sound sessions as well.
A variety of musical scales is offered to you, allowing you to choose
your favorite tuning.
Thanks to Andrey Mihaylov for the equipment.
