All definitions by Joe Monzo unless otherwise cited
proper, propriety
A function defined over the
interval matrix of a
scale, revealing the perceptual properties of that scale.
Strictly
Proper scales are those in which all intervallic size classes are
distinct and non-overlapping.
Scales in which two or more pairs of
interval classes contain identical members are Proper.
Scales with
overlapping or contradictory interval classes are Improper and are less
likely to be perceived as musical gestalts than proper or strictly
proper scales.
This concept of Propriety was introduced by David Rothenberg
(Rothenberg, 1969).
