One alternate tuning is published here, and it is here because it can be derived rather than asserted. The pitches, the semitone deltas, what the open courses spell afterwards and whether the shipped voicing library still applies are all computed from the registry's own G–C–E row by the same shared engine every site in this network uses, and recomputed independently by CI before this page ships.
The derived table
Every field below is arithmetic. "Moved" counts courses that change pitch; the reading is every triad the resulting open set honestly spells, not a nickname.
| Tuning | Courses | Moved | Open courses read as |
|---|---|---|---|
| A–D–F# | ADF# | 3 | D major |
Why only one
Treseros use other tunings, and they are absent for a reason this site states rather than hides: it has no source it can derive them from. A page here that published pitches somebody typed from memory would be worth less than no page, because every other number on this site is computed. When a tuning arrives with something to derive it from, it joins the table — and the retuning control and this page are held to the same set by CI, so neither can offer a tuning the other does not.
