The 11th Harmonic

What we have here is a simple 11 to 1 musical interval - the fraction represents a frequency ratio, in other words the higher note is eleven times faster or “higher“ than the lower note. After a bit of introductory business, we divide the frequencies arithmetically, which is incidentally the same thing as dividing the ratios, producing the following progression: 1:11 1:6:11 3:13:23:33 2:7:12:17:22 1:3:5:7:9:11 3:8:13:18:23:28:33 7:17:27:37:47:57:67:77 4:9:14:19:24:29:34:39:44 9:19:29:39:49:59:69:79:89:99 1:2:3:4:5:6:7:8:9:10:11 You math types might be able to notice a few patterns in those numbers!! Named after the Omnibus Romantic Progression of romantic times. About the software: Dorico mostly with some image editing. If you’re interested in software, I would say it’s much better to use something you’re already familiar with that might already have microtonal support - seriously check your vsts against this list, you might
