data Key Source

The following enumerated type lists all the keys in order of their key signatures from flats to sharps. (Cf = 7 flats, Gf = 6 flats ... F = 1 flat, C = 0 flats/sharps, G = 1 sharp, ... Cs = 7 sharps.) Useful for transposition.

data Scale Source

The Key Signature specifies a mode, either major or minor. Constructors Major Minor Instances Bounded Scale Enum Scale Eq Scale Ord Scale Show Scale Ix Scale Arbitrary Scale Random Scale

type ElapsedTime = Integer Source

defltST :: Tempo Source

defltDurT :: ElapsedTime Source

Default duration of a whole note, in seconds; and the default SetTempo value, in microseconds per quarter note. Both express the default of 120 beats per minute.
