Fun fact: 24-TET's step, at 50¢, is particularly interesting in that it is (theoretically) one of the most dissonant intervals possible.
In music theory, harmonic entropy is a model used to quantify how well chords and scales line up with the harmonic series (a simple way to think of it is as an attempt to definitively measure consonance and dissonance). Here, we have two key variables _a,_ which sets the order of the distribution used as the model, and _s,_ which is the linear frequency deviation.
The relatively common model of collision entropy sets _a_ = 2 and _s_ = 1.01, which results in the peak occurring at 46.4¢ (near 26-TET's step), and more generally, a critical range of between 40¢ and 60¢.
You'll find that people tend to perceive intervals smaller than 40¢ as being closer towards a unison, and intervals larger than 60¢ as having less "tension".

"And writing stuff that doesn't sound good is part of the process. Exhibit A:" **proceeds to play beautiful music which makes interesting use of the tuning**
The thing I like about 24-EDO is that it works seamlessly alongside 12-EDO, and can sound natural to people used to that tuning, but adds extra potential harmonies. It feels very rooted. Plus, I love the idea of being able to play it in a band setting without requiring everyone to have custom instruments. I've wanted to play around with it ever since I saw Adam Neely discussing it, I think in the context of how it can be used to give that "lo-fi hiphop" vibe.

Would definitely like to see a part 2 of this. A virtue of 24-EDO is that you can use existing 12-EDO instruments with it as long as the music doesn't call for them to play the half sharps and half flats and leaves that to the instruments that can play those notes. If you want to have a decent chance of symphonic music getting played using physical instruments, it is almost going to have to be in some multiple of 12-EDO.

Like Gdmaj7 or Fdbnem9/C#dim5

thank God for fretless strings

[@Lucius_Chiaraviglio]

@@samanthaqiu3416 They're good, but for symphonic works, you usually need winds and brass (trombone works in any tuning system, but not the others).

5:38 this part is my favourite

[@GMJ7320]

I would absolutely buy this - if it wasn't $4000.

The price is way too high for a synth, even with hegagon keys…

[@GMJ7320]

@@ZAWARUD00 it's only that expensive because it's specialist. tbf if you have no competition (like the lumatone), why wouldn't you drive the price up to insane degrees like this?

[@ZAWARUD00]

@@GMJ7320 To sell more of them? I'd wager that at half the price, more than twice the amount of persons would buy it

​@@GMJ7320And because the only keyboard layout that 99.99% of people are exposed to is that of the piano.

For years i’ve been using a slightly flattened major 3rd and 7th, inspired by Turkish music, and i just adore that sound. Got into microtonalism through an obsession with gamelan music decades back, it’s been a huge joy to see tools develop to make it easier to do! Used to have to make custom multisample instruments with individually tuned notes. We’re living in a golden age of music tools.

[@kpra.2pro590]

24 kinda wraps it up if this is the last one - but if it isnt it still is such a great tuning to discover n noodle around in - i love how you play different kinda stuff depending on the tuning itself and find out what styles it yields most in

[@kpra.2pro590]

so pumped for this series man

[@alexkoala18]

wow! it makes me feel something in the chest!!!!!!!

[@athuronyi]

So cool!

[@108Rudi]

Where can I find your music, Dave?

[@stancartmankenny]

2:41 I think that's used in stranger things somewhere.

[@yurysharov4499]

Dude could you just play it a little more... The second he started playing I felt something pleasant inside my head, something like a massage. I wish there was more microtonal music like this, a kind of music that feels both exotic and intimately familiar

'ajam and hijaz are maqamat that don't use quater tones
