Awesome Harmonicas

Composer and artist Sky Macklay shows off her Harmonitree, a wonderfully inventive musical instrument that plays harmonicas. It uses a tree-shaped inflatable airbag to push air through its harmonicas and can be left to make music on its own, but it is best when given a big hug for interactive sounds. She’s also built one that triggers with motion sensors.

Like a real harmonica, Lekholm’s musical tech senses its player’s breathing both in and out, but it outputs those modulations as MIDI signals for controlling synthesizers. The example performance is Cole Porter’s You’d Be So Nice to Come Home to, using a Yamaha VL70-m acoustic sound module.
