The simplest possible no-5's dekany. This creates a scale of 1 33/32 9/8 7/6 21/16 11/8 3/2 77/48 7/4 11/6 2/1, with steps of 33/32 12/11 28/27 9/8 22/21 12/11 77/72 12/11 22/21 12/11. This extends the basic archy scale of the 1-3-7-9 hexany into a 10 note detempered version of supra, with 6 perfect 5ths and plenty of consonant chords, although the lack of 5's and presence of many notes significantly smaller than a semitone make it obviously very distinct from 12edo.

Suggested keyboard mapping: Start on A, skipping the C# and F# notes, which puts the notes relatively close to 12edo on the white keys and the quartertones on the black notes.
