Boston

Boston is a 72-note scale which was discovered by Tristan Bay in 2024. Much like the way the Constructionsite scale does in the 7-limit, it covers the full 11-limit just intonation subgroup with just 5 different step sizes, the minimum amount needed: 81/80, 99/98, 100/99, 121/120, and 126/125.
