Description

Spelling rules for Interval values.

Synopsis

Documentation

i_to_interval :: Int -> Interval Source #

Simplest spelling for semitone intervals. This is ambiguous for 6 which could be either aug.4 or dim.5.

i_to_interval 6 == Interval Fourth Augmented LT 0
map i_to_interval [0..11]

interval_simplify :: Interval -> Interval Source #

Perform some interval simplifications. For non-tonal music some spellings are poor, ie. (f,g#).

interval_simplify (Interval Second Augmented LT 0) == Interval Third Minor LT 0
interval_simplify (Interval Seventh Augmented GT 0) == Interval Unison Perfect GT 1
