I'm very happy with the C major Hapi tuneable drum that I recently purchased from you.I have found it easy to tune and have so far tuned it to A minor and A akebono as well as the original C. I'm not a musician though have learned piano and guitar as a younger person. With this drum I can make some very relaxing and celestial sounds and even a few simple tunes which sound very nice to myself and my partner. Many thanks - I love it.
