Instances

class Eq n => Deg s n | s -> n whereSource

Methods

degrees :: s -> [(Degree, n)]Source

Returns all the naturally occuring Degrees in s, along with the element that corresponds to the Degree.

first :: s -> nSource

Returns the First Degree of s.

Instances

degree :: Note -> Note -> DegreeSource

Assuming n1 as the tonic, returns the Degree of n2.

from :: Degree -> Note -> NoteSource

Returns the Note that corresponds to Degree d in a scale where the specified Note is the tonic.

second :: Deg s n => s -> Maybe nSource

Returns the Second Degree of s.

third :: Deg s n => s -> Maybe nSource

Returns the Third Degree of s.

fourth :: Deg s n => s -> Maybe nSource

Returns the Fourth Degree of s.

fifth :: Deg s n => s -> Maybe nSource

Returns the Fifth Degree of s.

sixth :: Deg s n => s -> Maybe nSource

Returns the Sixth Degree of s.

seventh :: Deg s n => s -> Maybe nSource

Returns the Seventh Degree of s.

tonic :: Deg s n => s -> nSource

An alias for first.

supertonic :: Deg s n => s -> Maybe nSource

An alias for second.

mediant :: Deg s n => s -> Maybe nSource

An alias for third.

subdominant :: Deg s n => s -> Maybe nSource

An alias for fourth.

dominant :: Deg s n => s -> Maybe nSource

An alias for fifth.

submediant :: Deg s n => s -> Maybe nSource

An alias for sixth.

subtonic :: (Deg s n, Nte n) => s -> Maybe nSource

An alias for seventh, but only if the Seventh is a Min7th above the tonic.

leadingTone :: (Deg s n, Nte n) => s -> Maybe nSource

An alias for seventh, but only if the Seventh is a Maj7th above the tonic.
