middletuning
Middletuning is a theoretical concept in music theory that describes a tuning system where the interval of a perfect fifth is not perfectly pure, but is instead slightly tempered. This tempering is done to accommodate other intervals, such as the major third, which are often made more consonant in middletuning systems. The goal of middletuning is to create a more balanced and pleasing sound across a wider range of musical keys than is possible with simpler tuning systems like Pythagorean tuning.
In Pythagorean tuning, perfect fifths are tuned to a ratio of 3:2, which results in pure fifths
The practical application of middletuning is often seen in the tuning of historical instruments, particularly stringed
