Turntable that "plays" the rings of a tree

Bartholomäus Traubeck's "Years" is a modified record player that "plays" a slice of a tree, converting (and transforming) year ring data into piano music.

It is mapped to a scale which is again defined by the overall appearance of the wood (ranging from dark to light and from strong texture to light texture). The foundation for the music is certainly found in the defined ruleset of programming and hardware setup, but the data acquired from every tree interprets this ruleset very differently.
