The Sound Hole Kalimba (thumb piano) is pre-tuned to C Major scale and is fun for all skill levels. Pluck the keys in any order, and the notes will always go with each other (there are no wrong notes). These chrome plated steel keys produce soft melodies to create, relax, or meditate; plus, they‘re engraved with note information. The sapele wood body produces warm tone, and a sound hole gives the kalimba resonance. Features an engraved logo and design accent around the sound hole. Includes travel case, tuning hammer, and microfiber cleaning cloth.
