Mutation stops reinforce harmonics not aligned with the octave series

Evidence

Those stops that reinforce harmonics that are neither in unison (1:1) with nor a whole number of octaves away from (i.e., 2:1; 4:1; 8:1; … or 2n :1) the first harmonic are known as “mutation” stops. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1534 (#epitomizes, via linked claim)
