Equal temperament tuning made organ mutation stops sound beaty and unfashionable

Evidence

Equal tempered tuning thus colors with beats the desired effect of adding mutation stops, and therefore the inclusion of mutation stops tended to go out of fashion with the introduction of equal temperament tuning (Padgham, 1986). Recent movements to revive the performance of authentic early music have extended to the pipe organ, and the resulting use of nonequal tempered tuning systems and inclusion of more mutation stops is giving new life, particularly to contrapuntal music. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1562
