Spelling rules for Interval values.
- i_to_interval :: Int -> Interval
- interval_simplify :: Interval -> Interval
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
