My very first kalimba was a Treble. I had actually just come from a friend's house who had an Alto, and we'd all played the Alto and loved it - but when I went to the drum shop in Cambridge, Massachusetts back in 1986, they only had the Treble, with the 3rd note of the scale in the lowest tine (and not the root note, as in Altos). I bought it, but somehow I never really bonded with the instrument. A few years later, I got an Alto kalimba, and it was like day and night! I understood the Alto, with the root note as the lowest tine, and its range of exactly two octaves. (That is, the lowest note was "Do" of "Do Re Mi", and the highest note was also "Do", two octaves up.) With the Alto kalimba now in hand, my Treble was set aside. It eventually went to live with a friend, while I developed my long love affair with the Alto kalimba.
