I’ve always been intrigued by origamis. When I found out that the musical pitch space could be rappresented with a tapered helix, I became obsessed by the idea of modeling shapes and figures basing on intervals, both vertical and linear. I show above a rough example. We have three intervals (strating from the left a major seventh, an augmented sixth and a minor third). If we connect each pitch of each note to the closest ones in the staff, we obtain two tetrahedra joined by the segment corresponding to the middle harmonic interval. Each vertex of the tethraedra lays on a point of the helix pitch space. Doesn’t this boost your imagination? There are infinite possibilities! What do you think the classic origami crane would sound like after you put it inside the helix? ˆ-ˆ
