This composition was written for the 2010 60x60 Untwelve contest, which required microtonal compositions at most 60 seconds long. (My piece was not selected, though.) The piece explores some of the modulation possibilities of 17-tone equal temperament, namely the possibility to modulate to keys farther away (measured in steps on the circle of fifths) than would be possible in 12-equal. There is, e.g., a modulation to a key 8 fifths apart, the longest distance possible in 17EDO. (In 12EDO, the longest distance possible is 6 fifths steps). The tonality inside the keys is traditional-sounding minor, but the modulation steps are microtonal.
