The Bluebird original soundtrack album is now up on Bandcamp and will make its way to all the other platforms in due course. Here I'll say a few nerdy things about it.

The audio drama I co-wrote and did the soundtrack for is now out to buy. Kickstarter backers have all been fulfilled and it's on various platforms, or you can buy it more or less directly from us on Authors Direct. We're very proud of how it turned out. For my part, learning to master an audio drama was quite the experience and soundtracks are always an interesting challenge -- I think we made some difficult but good choices about sound overall, and it has a bit of a sonic identity of its own. The performers are all great. A soundtrack album is in the works that should be out maybe in November; I'll post an update here when it drops.

...in which I sift through 1,073,741,824 possibilities to find 12 interesting ones for the good of humanity. Results and some Scala tuning files inside.

The latest Minimum Labyrinth project is Bluebird, a ten-part audio drama with music by me. After about a year of exploring the ideas and then polishing and testing the script we're running a Kickstarter campaign so we can hire a studio and, you know, pay the actors and engineer a fair price for their labour. It went live today and ends on 8 April 2021 -- the project won't happen without backers, so if you're inclined to help make it happen please do. Some music nerd stuff follows below the fold.

Dividing the octave into 30 notes is an interesting proposition in part because 30 has the factors 2, 3 and 5, which means it contains a few smaller EDOs. In particular, it has three copies of 10-EDO that sit inside it like the three augmented triads (3-EDO) in standard tuning, and I've been working a lot with 10-EDO lately. But 30 notes is a lot to deal with, and far too many for me to play on a single keyboard. So in this post I muse about some ways to split 30-EDO up into more manageable parcels.

In 12EDO, the most interesting scales are (I think) the ones that use about half the notes: 5-, 6- and 7-note scales. In 10EDO, then, it makes sense to look at 5-note scales at least, and perhaps those with 4 and 6 notes. Today we'll look at all the available pentatonics in 10EDO and some relationships between them.

I'm currently working on a project involving mixing 10-EDO with symmetrical structures in 12-EDO. I thought it might be instructive for me to look at tunings that mix pitches from these two. The project is inspired by visionary modernist Paul Scheerbart so I've decided to call them Scheerbart Tunings. Free synthesizer (sort of) inside!

10 EDO divides the octave into ten equal parts instead of the usual twelve. We may as well number these notes 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. This is a pretty tuning that doesn't take too much getting used to. Let's create some harmony out of it.

We have been thinking about dividing the 12 notes of our ordinary tuning system (12-EDO) into two distinct regions, each of which is a whole-tone scale. Each region can be thought of as a tuning in itself, 6-EDO, the equal division of an octave into six notes. In this post we consider how the Augmented Hexatonic can help us bridge the gap between these two regions.

This post is a continuation of the last one in which we look at supplementing the rather limited whole-tone harmony with one or more added notes. The resulting chords take us away from "pure whole-tone harmony" in the same way that, for example, secondary dominants and other borrowed chords take us away from "pure diatonic harmony" while simultaneously enriching it.
