A pseudo-isomorphic pseudo-diatonic mapping for [[18edo]] that duplicates note 0 (as note 18) enables diatonic playing while keeping octaves level — it is the [[19edo]] diatonic layout, but with only 18 unique notes per octave. Alternatively, it can be interpreted as the 4L 3s | A pseudo-isomorphic pseudo-diatonic mapping for [[18edo]] that duplicates note 0 (as note 18) enables diatonic playing while keeping octaves level — it is the [[19edo]] diatonic layout, but with only 18 unique notes per octave. Alternatively, it can be interpreted as the 4L 3s Jankó layout above, but with a duplicate of note 0 added, which allows it to support both the 4L 3s scale (3:2 step ratio) and a 5L 1s<sub>1</sub> 1s<sub>2</sub> MODMOS scale (3:2:1 step ratio). This is demonstrated in [[Bryan Deister]]'s [https://www.youtube.com/shorts/hNmse4IUWL0 ''18edo improv''] (2025). | ||
