I just bought this tongue drum to play for fun but I was amazed at how many sounds I could make with it. It has lows, mediums, and highs. Some may call this a pentatonic scale instrument. I'm not too familiar with the terminology but I do like playing this instrument! It's very calming and relaxing to play! Great for beginners and kids! I'm sure there are better instruments of this kind out there but for the price this isn't a bad deal at all. Highly recommend!
