This page presents a novelty topic. It may contain ideas which are less likely to find practical applications in music, or numbers or structures that are arbitrary or exceedingly small, large, or complex. Novelty topics are often developed by a single person or a small group. As such, this page may also contain idiosyncratic terms, notation, or conceptual frameworks.

This user page is editable by any wiki editor. As a general rule, most users expect their user space to be edited only by themselves, except for minor edits (e.g. maintenance), undoing obviously harmful edits such as vandalism or disruptive editing, and user talk pages. However, by including this message box, the author of this user page has indicated that this page is open to contributions from other users (e.g. content-related edits). Author comments: Feel free to add examples of music made with this scale, and feel free to add any new scales, approaches or other concepts you develop based on these ideas.

The breuddwyd-6 scale^{[idiosyncratic term]} is a polymicrotonal scale. Breuddwyd-6 is created by including all the intervals from the scales 5ed6, 11ed6, 13ed6 and 31ed6.

It belongs to a collection of scales called the breuddwyd scales.^{[idiosyncratic term]} Its equave is 6/1, and it has 57 notes per equave - so about 19 per octave on average.

It approximates the full 11-limit quite well.

Snow braid scale

The snow braid scale^{[idiosyncratic term]} is a 37-tone subset of the breuddwyd-6 scale.

Its name derives from the iceface tuning because that also contains an even mix of 12edo-like intervals with xenharmonic intervals.

The snow braid scale approximates the full 11-limit quite well.

Its equave is 6/1, and it has 37 notes per equave - so about 12 per octave on average. It can be viewed as a well temperament of 37ed6. Ed6s with exceptional approximations of snow braid for their size include: 168ed6 (8.4¢ err), 195ed6 (7.2¢), 196ed6 (7.2¢), 235ed6 (6.0¢), 288ed6 (4.9¢), 289ed6 (4.9¢) and 341ed6 (2.1¢).
