RE: [Harp-L] Why use the term "perfect" to describe a perfect fourth ora perfect fifth?

["Joe Phillips" <jphillips@xxxxxxxxxxxxxxxx>]

In addition to John's definition, there are some interesting
characteristics of the perfect interval. When inverted the interval
remains perfect, unlike the behavior of the major, minor, augmented and
diminished intervals. Raised a half step, a perfect interval becomes
augmented, as a major interval does. Lowered a half step, it becomes
diminished, as a minor interval does. But the behavior of the major and
minor are not similarly symmetrical.
