V: CHORD PAIRS FROM SET-CLASSES WITH LOW RECREL VALUES
conclude the study, let us examine a group of chord pairs. The cases
constituting Example 9 are derived from pairs of SCs that the RECREL similarity
measure deems highly similar. The values vary between 0 and 10. SC pairs with
values this low have a very small representation: the pairs within the range 0
– 10 constitute just 0.11% of all pairs (see Castrén 1994:128).
There are nine comparison groups #n/#m, 3 ≤ n, m ≤ 7,
containing SC pairs with RECREL values 10 or under. Ex. 9 gives at least one
chord pair representing each of these categories. When the chords are of
different cardinalities, the one with more elements is given first. The RECREL
value is given below the SC names.

 The RECREL value indicating highest degree of similarity is 0. Two SCs with this value have identical proportioned subset-class contents. The value indicating highest degree of dissimilarity is 100.
