Astronomia by Tony Igy — yes, that meme tune — turns unexpectedly lyrical on kalimba. The tab is only about half a minute long, so learning it whole is a matter of one or two sessions.

The arrangement makes heavy use of all four low tines of a 21-key kalimba (F3–B3): the bass is half of what makes it recognizable. On 17 keys, use the transpose suggestion in the banner. The rhythm is strict and electronic — keep it even, with the metronome enabled in the player settings.
