Tuning in musical context

Not one system for every situation

After the purity comparison, this lesson does not repeat individual cent values. It places the systems musically: equal temperament, local just intonation, and historical temperaments solve different problems.

Equal-tempered

A stable grid for modulation, fixed-pitch instruments, and shared reference thinking.

Just

A local sonority is shaped according to its current harmonic relationship.

The key idea: tuning is not only a table, but a musical decision in context.
