I've decided to try building a nail organ with a view to gigging it at an event I'm speaking at anyway in the spring. Here's a bit of background and where I got to this afternoon.

Here's a kind of cheap trick using coscales, because sometimes you just want a good sound without having to work through reams of stuff to get it.

Neetimati and Gayakapriya are Carnatic scales that have come up a few times on this blog, but that I've never really dug into. In my last post I discovered they share a slightly obscure property; on closer inspection it turns out they have a close and musically useful bond.

Every scale has twelve transpositions, some of which are modes and some hypermodes of the original one. Unless the scale has only one note in it (!) there will be some overlap between the original scale and at least some of its transposed copies. Indeed, for seven-note scales, one of the most common categories we work with, every transposition will share at least two notes in common with the original. Let's see if we can use this to our advantage.

For a while here I've been publishing page after page of chords, which is something I hardly ever used to do. It's probably time for an explanation.

Messiaen's Mode 6 is a symmetrical scale that can be made by adding two notes to the Whole Tone scale. Adding one of these gives us Neapolitan, so I thought it was probably time to look at the other one.

This post came about because of a reader's request by email, referring to an unfulfilled promise at the end of this venerable post. There I said I wanted to get round to writing about how the abstract picture of modes can translate into something concrete on the fretboard.

There are only three octatonic ("half-whole") diminished scales, and two have reasonably well-known applications over everyday chords. What about the third?

Samuel Andreyev has just done a nice video about Hindemith that reminded me of how much I like him. He's also a great antidote to all the misty, smeary, billowy late-Romantic/Impressionist stuff I've been listening to lately so I thought it would be worth doing a round-up of some good things in the same vein.

Yesterday I posted some initial thoughts on the "whole tone dominants" -- those altered dominant chords that are subsets of the whole tone scale. The obvious other thing to do, particularly with my current obsession with Scriabin, is to look at the "octatonic dominants" that come out of the half-whole (or whole-half) diminished scale. Caveat: this post is a bit of "primary research" -- not very exciting as at stands, but with potentially useful applications.
