Lumatone mapping for 27edo: Difference between revisions

Line 2:

== Diatonic ==

[[Gordon Wery]] has created a pseudo-diatonic mapping that flips the direction of the two semitones, which can also be interpreted as a [[terrain]] mapping. This extends the range to slightly over 6 octaves at the cost of making the diatonic scale slope heavily upward and wrap around to the bottom again repeatedly. The .ltn file for this can be downloaded [https://drive.google.com/file/d/1zNTk7FGrNo8k5zSAmOWYiK2x4CK4fjjJ/ here].

== Tetracot ==

Keep in mind that 27edo is a [[superpyth]] temperament, so 5/4 is mapped to the interval of an augmented second (e.g. a 5/4 above C is D♯). Therefore if 0 is 1/1 on this mapping, 9 represents 5/4 and you can find that by going over to 5 {{nowrap|(e.g. C → D)}} and then going up to 9 {{nowrap|(D → D♯)}}. If you want {{nowrap|{{dash|root, 3rd, 5th}}}} triads to be accessible in a more intuitive way, the [[7L 6s]] mapping for [[Tetracot]] may be preferable.

== Myna ==

If you want to maximise your range, the [[myna]] one is the widest one that still covers the whole gamut, spanning 8 octaves ~~in its most compressed MOS. Though,~~ the [[4L 3s]] ~~MOS has a 6:1 step ratio, making it quite awkward~~.

If you want to maximise your range, the [[myna]] one is the widest one that still covers the whole gamut, spanning 8 octaves using the [[3L 1s]] mos scale.
