Arbor Musicae – Tree of Music
Tree + Violin = Musical tree! Did you know there really are string instruments played by the wind? They’re called aeolian harp or wind harp, really cool!
Here is my fantasy take on this concept. My initial idea was combining the functionality of a violin with a tree to create sound, but I also explored non-string ways of doing so, using vibrations from other sources like animals, or objects hitting a hollow tree trunk.
