Sevish — Plot Hole

22 tone JI

Track one from the album Bubble [2021], atmospheric drum and bass: https://sevish.bandcamp.com/album/bubble​

The scale used here is an approximation of 22edo using select harmonics between 128-256. All intervals are therefore some number over 128 and the scale is near-equal. In a sense all notes in the scales are related to some very low fundamental frequency. This 'justifies' the sound of the tuning somewhat but also allows for free modulation like you would expect from an equal scale.

The idea to experiment with this kind of tuning came from the short story A Bit O' Blarney by George Secor. But these days the idea is being popularised by Zhea Erose and various members of the Xenharmonic Alliance Discord.

From 0:58​ the 4 chord progression modulates up by a minor 3rd (6\22) each repetition. In 12edo, this progression would return to its original key after 4 modulations, but in quasi-22edo (and 22edo) you end up in a key a semitone higher than where you started. That's because the minor 3rd is tuned wider, so the difference starts to really accumulate as you stack the same interval repeatedly.

Sevish — Almighty Fractal

Just Intonation (JI) ambient

Lofi ambient from my album Bubble [2021]: https://sevish.bandcamp.com/album/bubble​

Almighty Fractal uses a tetrachordal scale (same as 'The Entity Unmasked', see Scale Workshop link below). It is mostly one improvised take with overdubs. A nice property of small 'modal' sounding scales is that you can just jam and improvise easily. I intend to explore this approach more in some of my future music.

Fractal animation done with Mandelbulber plus Kdenlive. Sorry that youtube compression mushes it - I can't help but have fast moving details in my fractal vids. Maybe I should upload the full resolution versions some time.

Brendan Byrnes — Microtonal Guitar Etude and Demonstration — 27 EDO

This is a short piece for a guitar fretted to 27 Equal Divisions of the Octave (27EDO) and an informal demonstration of some of the interesting chords and intervals in this tuning system. The guitar was refretted by Metatonal Music.

Brendan Byrnes — 2227 [LP] (only pre-order yet)

A preview clips set of all tracks and one full track are released. The full album releases May 28, 2021.

“xenharmonic music uses tuning systems that neither conform or approximate the common 12-tone equal temperament”

This music uses 22 and 27 equal divisions per octave (EDO) tuning systems. Custom fretted guitars by Metatonal Music and retuned synthesizers made possible by H-PI Instruments.

Sevish — Dream Up (Demo Version)

JI

https://youtu.be/lTT3QGTngIs

An early DEMO version of Dream Up that I thought would be interesting to share. Faster tempo. Brighter tuning. Different sound designs. Less finesse overall.

The tuning is 140., 200., 310., 400., 540., 640., 700., 833., 900., 1040., 1100., 1200.
