Hokema Kalimba B15 Glissando Improvisation

The new Hokema B15 Kalimba is wonderful. It's unique layout makes it very easy to sound good even without understanding music theory.
The bottom left tines goes great with the top right, and the bottom right tines goes great with the top left tines.
The two layers of tines also makes it easier for me to know which tine does what, not confusing them with their neighbors.
