== Semiquartal ==

~~To maximise your range while keeping octaves near horizontal, use the~~ [[4L 1s]] ~~layout~~.

The [[4L 1s]] Semiquartal mapping gives you an even wider range, is a fraction of a cent off the 9-odd limit minmax tuning for [[beep]] temperament using the ccd val and is also a significant non patent tuning for [[godzilla]].

== Sephiroth ==

To maximise your range while covering all the notes and keeping octaves near horizontal, use the [[3L 1s]] layout.

== Augmented (triforce) + bohpier Lumatone mappings ==

[[Bryan Deister]] has demonstrated two mappings for [[33edo]] that function for the temperaments [[augmented (temperament)|augmented]] ([[triforce]], 33d val, [[3L 3s]] scale with 7:4 step ratio) and [[bohpier]] (33cd val, [[8L 1s]] scale with 4:1 step ratio). The down-right (forward chroma version) or rightward (reverse chroma version) generator is a somewhat flat Alpharabian tendoneutral second ~[[12/11]] which can be stacked to get several consonant intervals; however, some of them map inconsistently. Two of these generators make a near-just neogothic minor third ~[[13/11]], mapped consistently. Three of these generators make a near-just septimal major third ~[[9/7]] by sound, but the mapping only works if 9/7 is constituted as (3♭ × 3♯) ÷ 7 or as 9 ÷ 7♭ (33d val). Four of these generators make a near-just lesser septimal tritone ~[[7/5]], mapped consistently ([[patent val]] or 33cd val). Six of these generators make a flat classic major sixth ~[[5/3]] by sound, but the mapping only works if 5/3 is constituted as 5♭ ÷ 3 (33c val). Seven of these generators make a near-just classic minor seventh ~[[9/5]] by sound, but the mapping only works if 9/5 is constituted as (3♭ × 3♯) ÷ 5 or as 9 ÷ 5♭ (33c val). The range is a bit over six octaves in the forward chroma version or five octaves in the reverse chroma version; in both cases, the octaves slope moderately downwards resulting in a vertical wraparound.

=== Forward chroma ===

Demonstrated in [https://www.youtube.com/shorts/mkaaAJEyGFU ''33edo riff''] (2025).

=== Reverse chroma ===

Demonstrated in [https://www.youtube.com/watch?v=GypR6x_Ih1I ''33edo jam''] (2025).

== Oneirotonic/Antipentic ==

[[Bryan Deister]] has demonstrated a mapping for [[33edo]] that yields both [[5L 3s]] (oneirotonic, 6:1 step ratio) and [[3L 2s]] (antipentic, 7:6 step ratio) scales, in [https://www.youtube.com/shorts/Lf0CCX88w_w ''33edo improv''] (2025). The underlying temperament is [[Buzzardsmic_clan#Buzzard|buzzard]], which treats the sharp fifth as ~[[32/21]] and makes both sharp and patent fifths almost as easy to access. The range is a bit over 4⅔ octaves, with a fair number of repeated notes to mitigate vertical wraparounds and the octaves slope moderately downwards.
