Boobams were developed in the 1950s as fully chromatic sets of drums. They were used in the orchestra pit for shows like The Pirates of Penzance. However, they fell out of favor because they were hard to tune and maintain. My colleague asked if I could come up with something for a piece she was working on since it required Boobams. It turns out they are a perfect companion to the Joia Tubes and also as a stand-alone instrument for music education.
