1994 release (VERY RARE) **  "This important and rare CD was produced by Jonathan and Elizabeth Glasier, Gary Morrison, and Brian McLaren. This is the only extant permanent document of Darreg's work. Includes original booklet with reproductions of tuning charts. Ivor Darreg (1917-1994) was interested in both just intonations (tuning systems based on the ratios between the frequencies of the pitches) and equal temperaments (tunings with pitches equally spaced through the octave, which require a different mathematical approach). He was fascinated by the unique aesthetic effect – the characteristic “mood”, in his word – created by each tuning. The charts included in this exhibit are representative of his tuning graphics. As an instrument maker he created another sort of tuning graphic in his Megalyras. These were two- or four-sided string instruments, playable with a slide, with the slide locations for various tunings laid out in full color along the necks."
