Being in the flattone part of meantone, and indeed at the flat end of flattone itself, 26edo requires some adjustment to convert common practice music to sound right, and what is technically a diatonic layout (although fairly extreme in its softness) may require different usage than in a more middle-of-the-road diatonic tuning. YoVariable demonstrates this mapping in Jingle Bells (26edo microtonal Lumatone cover + Mystery Song) (2025).

Orgone
However, 26edo is a flattone system that does not have very accurate 5-limit approximations, so other options are probably preferable. If you want to maximise the playable range and put the best consonances close to each other, the orgone mapping is the clear winner.

Other mappings
The Lemba and Hendec mappings also work particularly well in 26edo.
Lemba
Bryan Deister has demonstrated this mapping in Waltz in 26edo (2025), and explains that right and up yields the minor third (~6/5, fairly sharp) and right three times yields the fifth (~3/2, fairly flat).
