The [[Whitewood]] mapping is the one that functions in the closest way to the familiar diatonic scale.
The [[Whitewood]] mapping is the one that functions in the closest way to the familiar diatonic scale. The actual near-diatonic scale is [[5L 3s]] with a 3:2 step ratio (oneirotonic), and this mapping is demonstrated in [[Stephen Weigel]]'s [https://www.youtube.com/watch?v=hxPJt812VDA''Iridescent Wenge Fugue''] (live performance version, 2026, with oneirotonic colors). Scales [[7L 7s]] (2:1 step ratio) and [[3L 6s]] (3:2 step ratio) are also supported. The range is 4⅓ octaves, and the octaves slope upwards with the rows, or gently downwards with the oneirotonic scale.

Since the 7th harmonic is the lowest one that is accurately tuned, the [[gorgo]] mapping works well for creating consonant combinations of notes, and also has a wider range.
Since the 7th harmonic is the lowest one that is accurately tuned, the [[gorgo]] mapping works well for creating consonant combinations of notes, and also has a wider range (nearly 7¼, with a slight upward slope). [[Bryan Deister]] demonstrates this mapping in [https://www.youtube.com/shorts/9a-nJ_Ml9z8 ''21edo groove''] (2026).
