Here's another quote, different author, who quotes a third author:
I might have also said originally: if you agree, could you please provide an example of "greater musical interest" BECAUSE of rule breaking; if you disagree, could you please provide an example of "greater musical interest" DESPITE following rules.
"The opinion that c-C# is the lesser semitone, and C-Db the greater, is doubtless
productive of serious mischief. The reverse is true. Assuming C at 256 vibrations, an absolutely
pure Db has 268.04, while a pure C# has 273.0375 vibrations. The minor second is therefore materially
narrower than the augmented prime.
