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 repeated.
