I am Burkhard von Stackelberg, an ambitious musical hobbyist living in Stuttgart. Not the one in Kansas nor the one in Arkansas, but the much bigger one in Germany. While I mainly compose in 12edo (or, let's say, my music is mostly interpretable and understandable in 12edo), some of it is microtonal. Like most of us, I am grown up in a 12edo context culture, and most instruments I deal with strengthen a 12edo position, but in electronic music I like to use a bunch of possibilities, of which 12edo is but one.

'''[https://soundcloud.com/user-824310486/jolly-ride Jolly Ride]''' is a piece written in the equal-tempered Bohlen-Piercescale (13ed3). Using an eclectic musical language from baroque, jazz/ragtime, and impressionism, I tried to shed light on the possibilities of BP. Using mostly the lambda scale as a base, modulating between different tonalities, I also use False Father with its pseudo-octave at one point. BP is mostly known as a scale with low tension, I found that there is more in it. Enjoy a jolly ride on an exoplanetary camel!

Tuning recipe: Start with a 9:10:11 chord. Repeat it all over in 7:9 periods. While giving you savvy 7:9:10:11 harmonies, it lacks a clear octave period, forcing you to seemingly polytonal settings.

How many notes does one need to make music? Here, I used no more than 4 in a 1:3 range, at intervals barely less than a Fourth in traditional western notation. Or about half a 5-equal division of the octave.

Experimenting in the neighbourhood of diatonic JI, I found some scales with astonishing similarities in the way they can be build, leading to a whole scale family with low harmonic entropy.
