Writing music with Alda #1: your first notes
Every now and then, somebody tells me that they just installed Alda and they’re enjoying it, but that they aren’t quite sure where to start when it comes to writing a piece of music.

Minutiae #1: Alda stuff, Clojure tooling for Vim
I’ve been meaning to update this blog more often for a long time now. The problem I have is that I have a lot of interesting things that I could write about, but I feel like it would take so much effort to produce a blog post worth reading, I just never have the time to do it. As a result, I’ve ... (more)
