== The Accuracy Fever Dream == | == The Accuracy Fever Dream == | ||
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'']. | 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).

== 30edo (demonstrated to work) == | |||
[[Bryan Deister]] has used a layout for [[30edo]] that was inspired by the layout for [[29edo]], as demonstrated in [https://www.youtube.com/watch?v=NP3HGr3ZD70&lc=UgxFBmbxZa5dF4ZPj0F4AaABAg.AFzcn1LkVZNAG4JYIvXZvZ ''minuet in 30edo''] (2025). The right-moving generator is a somewhat flat Pythagorean whole tone (~[[9/8]], 5\30; and in the video, the lines that include note 0 are colored red with light pink cores). The up-moving generator is a somewhat flat tridecimal supraminor second (~[[14/13]], 3\30); neither would be able access the full gamut on its own, but together they cover the full gamut with a generous allotment of repeated notes. The range is a bit under six octaves, with octaves slanting up (wna wrapping around) at the same angle as the right-moving generator. | |||

The comma |-33 -1 0 0 10⟩ (11.224¢) equates a stack of ten 11/8 (octave-reduced) to 3/2. However, this only gives the patent fifth in more or less the range 35EDO to 37EDO. For 50EDO (as noted above) it gives the Blackwood (pentatonic) fifth; while for 46EDO it gives the 23EDO flat fifth. | The comma |-33 -1 0 0 10⟩ (11.224¢) equates a stack of ten 11/8 (octave-reduced) to 3/2.

Even after the above gets its own space on a temperament page (if that ever happens), something I would like to see (but have no way to generate myself) on the 11L 2s page would be a musical samples akin to what [[5L_3s#Samples|the 5L 3s page has for musical samples]]. Ivan Wyschnegradsky wrote a considerable volume of diatonicized chromatic music, including ''Préludes dans tous les tons de l'échelle chromatique diatonisée à 13 sons'' (24), for 2 pianos in quarter tones, Op. 22 (1934, rev. 1960). If a short one of these works (such as one or two of the ''Preludes'') could be gotten in MIDI form and processed through a synthesizer with a high-quality piano emulation in various tuning systems (as noted in the temperament discussion above), this would provide an excellent Musical Samples section for this page. | Even after the above gets its own space on a temperament page (if that ever happens), something I would like to see (but have no way to generate myself) on the 11L 2s page would be a musical samples akin to what [[5L_3s#Samples|the 5L 3s page has for musical samples]].
