I just bought the "A Integral" Handpan from RAV Vast. I really love this instrument. Though there are limitations in the tone range it's really beautiful and well crafted instrument wich a rich and deep tone that a Smartphone mic can't really pic up. I've recorded an idea which is more about the chord movement than about a strong melody.  Tuning: A2 C3 E3 F3 G3 A3 B3 C4 E4
