Bartholomäus Traubeck, a composer from Vienna, Austria, has figured out how to translate tree rings into something akin to music. Traubeck uses technology to create “music” from the ring data on slices of seven different tree species. Listen to this piano piece by an Alder Tree:

Here’s a description of the process on Traubeck’s BandCamp profile:
A tree’s year rings are analysed for their strength, thickness and rate of growth. This data serves as basis for a generative process that outputs 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.
And just for the heck of it, here is one other of my favorite Tree Songs from the same album, the music of an Ash (Fraxinus) Tree:
