The Meinl Sonic Energy Solid Kalimba, sometimes called a thumb Piano, is a soft-sounding melodic instrument that fills the space around you with ethereal tones. This kalimba has 10 steel keys (tines) in the scale of C major. This instrument is easy to play and does not require any musical background. It's great for sound healing therapy, meditation and yoga, as well as teachers for corralling a classroom. Of course, musicians can have their fun with them, too. This Kalimba comes with a protective case that's great for traveling and features an exquisite "Tree of Life" carving. Also included is a tuning hammer to make adjustments as needed (the kalimba comes pre-tuned), a microfiber cloth for cleaning and a linen storage bag.
