Let’s go 19-EDO 👏

Not super-important, but I also use white for naturals, and red and blue for single-accidentals. However, I use red for sharps and blue for flats. That, in the sense that sharps are “hot” and flats are “cold.”

You should do a 22-EDO Chord Shapes video next! It’ll be interesting since 22 is a non-meantone tuning. Rather, it is a superpyth tuning, and some familiar chord shapes will be played differently from their meantone counterparts :)

Can the Lumatone be used for equal divisions of intervals other than the octave? For example, I would be interested to hear what 19 equal divisions of the pure twelfth would sound like, which would be similar to 12 edo but would result in slightly stretched octaves more like how real pianos are tuned. Each step would be the 19th root of 3.

First! Have my own Lumatone coming soon :)

You need to do full Songs :l These Shorts are so unique but too short

Another important ... frontier? ... to add to these videos is inversions. (Well, obviously, inversions are hardly a "frontier," but I think they're worthwhile demonstrating to add to the chord-shape library, both just for the shapes, and to demonstrate the effects upon their sounds in various tunings.)

The 12 notes are NOT "EQUALLY DIVIDED". They are a group of 12 notes from 20 Equally divided notes. I tune by frequency. I can get 19 notes , 20 notes, and 21 of the most pleasing notes to the ear that 12 have not because 12 notes are equally divided. You are thinking of 12 EDO. 12 Equal tempered notes are not equally spaced. It is the tempering of the 12 notes by only the shear physical placement of the 12 frets on a guitar. As it is justly placed if you align the frequencies properly. You cannot rule note selection by cents. You are always forcing A to be 440 and C to be what it is in 12 equal tempered. 12 TET or 12 ET. With this formula it is impossible to create the correct note selection in frequency. Cents and frequency are not linear starting at any frequency. However they are aligned with only specific set of frequency. The PHYSICAL fret placement on standard mass sold guitars are derived by the 12th square root of 2. Not anything else. This only works with select frequencies. Namely 12 TET or 12 ET. However it is also a just fractions placement when aligned to 240HZ as B. Thanks. And your welcome. I am awaiting my pulitzer prizes for my box of works of frequency alignment and EDOs. Many of you may have been taught only the sold teachings by that i mean you bought poop of uselessness. i am and my books shall reveal to you the word and works of the holy lord thy holy holy holy GOD. I am that i am. And am the very election 144,000. For I.E. = the 12 frets on a guitar can produce different fractions based on frequency alignment. For instance i can derive the notes by the perfect fifth 1.5 ratio or 12 ET at 1.4983072071etcetc. Thus it is proven, the frets can be aligned by frequency and fractional equations. And A doesn't must be a thing and C another and all must fit to that. That is not how it is done. Just saying for anyone learning this microtonal enrichment. Music can be enriched, it doesn't have to sound out of tune just because it is microtone. Your peices sound great though. Thanks for your video.

if i had the money

This keyboard was designed for autistic people. The shape and the names of the chords just make sense.

For a confused man like me, I feel this can be a gift for babies below 3 years old. As whatever key they press with finger/palm it will sound "something"😂
