Thai, Burmese, Indonesian, Turkish, and African music feature alternative tunings, and the microtonal variation of intervals are staples of spirituals, blues, and jazz. The resulting soundscapes are often haunting, and even discomfiting, to the ear of Westerners used to listening to 12-tone compositions. Several designers have successfully used 3D printing technology to make musical instruments the projects have been limited to creating replicas of existing instruments which feature normal intonation. A group of researchers from the Science and Music Research Group, University of Glasgow have modeled and designed and printed a microtonal clarinet, and you can read the whole story about this experimental microtonal clarinet here: http://3dprint.com/30497/3d-printed-microtonal-clarinet/


Below is a look at the OpenSCAD rendering of the clarinet:
