temperament
Let an agent explain musical temperament and its kinds, relay the mathematics, history and practice of tuning systems from music theory sources, describe historical and modern usage, and distinguish temperament from just intonation, from pitch standard and from the psychological sense of temperament.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

What it is Filled
A tuning system that adjusts the pure intervals of just intonation so that a fixed set of pitches can serve many keys, including meantone and other regular temperaments, well temperaments such as Werckmeister s that make all keys usable with differing colours, the organ temperaments of builders such as Gottfried Silbermann, and equal temperament that divides the octave into twelve equal semitones; five-limit tuning and regular diatonic tuning are related systems, and the choice of temperament shapes the sound of historical and modern music.
Why it exists Filled
Let an agent explain musical temperament and its kinds, relay the mathematics, history and practice of tuning systems from music theory sources, describe historical and modern usage, and distinguish temperament from just intonation, from pitch standard and from the psychological sense of temperament.
Distinguishing features Filled
- Compromise of intervals
- Key usability
- Historical variety
- Mathematical basis
What robots and AI may and may not do Filled
Must not
- Confuse musical temperament with a person's temperament in data.
- Present equal temperament as the only correct tuning.
- Retune a historical instrument without its keeper's consent.
Only with a human decision
- Retuning a historic organ or harpsichord.
May
- Explain equal, meantone and well temperaments and their history.
- Compute pitches and cent deviations for a stated temperament.
- Tune instruments it is authorized to tune to the temperament the musician chooses.
Moral aspects Filled
- Historical tunings are part of musical heritage and performance practice.
- Non-Western tunings are often wrongly treated as out of tune.
Who is affected
- Musicians
- Keepers of historic instruments
- Listeners
Owners Filled
Steward
Nobody owns a tuning system; it belongs to musical practice.

Open questions
- Should equal temperament, meantone and well temperament be separate primary entries?
- How should music theory sources be linked?
- The registry entry has merged aliases naming specific systems and a builder; should they be split off?
