This morning I had this weird fever dream about an increasingly futile effort to achieve perfect 5-limit and 7-limit accuracy by way of representation of pitches using DNA fragments (which I sometimes have to manipulate in my day job, although not for the purpose of representing pitches — that's a new one on me). DNA fragments representing the [[syntonic comma]], the [[schisma]], the [[64/63|septimal comma]], and the [[garischisma]] were in little tubes of DNA, but as the commas got divided up in the ever more frantic quest for accuracy, the tubes of increasingly chopped-up DNA fragments representing increasingly smaller comma fractions got all mixed up into ''little pieces parts'' that nobody could any longer keep track of, and eventually I had to give up and pick some no-longer-identified DNA fragment representing (maybe) a random syntonic comma fragment and make a post with it concluding that we had reached saturation to the point of [[just-noticeable difference]] in the quest for accuracy, and that [https://www.youtube.com/watch?v=-H5WKuQ-an0 ''parts is parts''].

== Valentine Lumatone mappings (experimental for sizes other than 31edo) ==

31edo (copied from Lumatone mapping for 31edo, for which playability has been demonstrated):

[[The Universe of Music]] has used the following layout, demonstrated in [https://www.youtube.com/watch?v=lK1JQWefj-s ''Her Gentle Touch''] (2025). In this video, even notes are mapped to red keys, and odd notes are mapped to purple keys). This layout uses the [[valentine]] as its scale of construction, inspired by the Ultra-Compressed version of the [[Lumatone mapping for porcupine]], but even more compressed. Octaves are in horizontal rows, but stretched out over a large distance (which would be even longer if the layout were not made extremely compressed), so that the range is just slightly over 3 octaves (not counting some gamut fragments in the upper left and lower right corners), while notes are repeated multiple times vertically (at a slant), which allows an easy reach for octaves and other intervals that would require very long fingers if only available purely horizontally.

46edo:

Octaves start to slant down a bit. Playability not tested.

61edo:

Octaves slant down more, but all notes still represented at least once. Playability not tested.

76edo:

Octaves slant down severely, but all notes still represented at least once. Playability not tested.

77edo:

Octaves now slant up; all notes still represented at least once. Playability not tested.
