B11 Melody Kalimba
Playing this instrument is like a burst of joy. It is a great personal instrument and travels well. For adults or older children.
The B11 "Melody" Kalimba, made by the same people who make the Sansula, is a much more capable instrument. It is in the key of G, which is generally useful, and has a range of G3 (G below middle C) to A5 (two octaves and a whole step above the lowest note). The two octave range is important. The lower octave is sparsely populated, which makes this good for accompaniment. The upper octave has every note in the G major scale, plus one more note in the high A, which means there are a lot of melodies you can play on this instrument.
