Blackdyasem

Blackdyasem is a 7-limit just intonation scale which contains both a single pental blackdye pattern and a single septal (2.3.7 subgroup) diasem scale pattern within it. It is constant structure and is a detempering of 19c, and is the predecessor to the similarly-named Blackdiasem scale.
