I've been playing the kalimba intermittently for a couple of months, and more seriously (~15min/day) for the last week. I've gotten moderately better, from zero to a somewhat stumbling Cruel Angel's Thesis.

I strongly expect I will continue to play ~15min/day. I'll probably look up "learning kalimba" resources but not spend money on it. On Jan 1, will I feel like I've substantially improved in my ability to pick up new songs, compared to now?
