This video features several instruments built around sets of stopped fipple pipes with different sorts of player interface: harmonica-style mouthpieces, small tappable bellows, and keyboard. For more instruments by Bart Hopkin, visit the instrumentarium at www.BartHopkin.com, or look for other videos in the Bart Hopkin YouTube channel.
And by the way! Bart has recently released an album of his music, made primarily on instruments he's made. It's called Audiorium, and it's available through the usual download and streaming services.
