Tenkan (Hybrid Harmonic Flute)


The tenkan is a hybrid harmonic flute created by Alcvin Ryuzen Ramos. It combines the mouthpiece and blowing subtleties of the shakuhachi with the circular breathing and rhythmic dynamics of the yidaki (didgeridoo). Alcvin has named this instrument, “tenkan” which translates as “heaven flute”. The 5 finger holes which are positioned towards the top of the flute and its length which starts at 3.65 and can be as long as 7.5! The length is what creates the wild harmonic frequencies giving it a very exotic, otherworldly tone quality. Made of Queens Tears bamboo and Black “Northern Shaolin” bamboo. Orders accepted.

The tenkan has greatly helped me with my shakuhachi embouchure, and also refining my breathing practice. It has taught me refinement and subtlety. It also sounds incredibly beautiful and is fun to play! Thank you so much Al for creating such a fantastic instrument!
