The philosophy of MEINL's Sonic Energy series is to better appreciate how sound lives, moves and breathes among us in every moment of our lives. This high-quality range includes many instruments that are tuned to specific frequencies, like this cool 17-note soundhole kalimba. It can be used for massages, spas, sound therapies and in many other musical environments. It's less about performance, and more about embracing the powerful energies of sound, and the positive impact it can have on our mental and even physical health.
