---

mingus.core.keys.couple

Attribute of type: tuple ('C#', 'a#')

---

mingus.core.keys.keys

Attribute of type: list [('Cb', 'ab'), ('Gb', 'eb'), ('Db', 'bb'), ('Ab', 'f'), ('Eb', 'c'), ('Bb', 'g'), ('F', 'd'), ('C', 'a'), ('G', 'e'), ('D', 'b'), ('A', 'f#'), ('E', 'c#'), ('B', 'g#'), ('F#', 'd#'), ('C#', 'a#')]

---

mingus.core.keys.get_key(accidentals=0)

Return the key corrisponding to accidentals.

Return the tuple containing the major key corrensponding to the accidentals put as input, and his relative minor; negative numbers for flats, positive numbers for sharps.

---

mingus.core.keys.get_key_signature(key=C)

Return the key signature.

0 for C or a, negative numbers for flat key signatures, positive numbers for sharp key signatures.

---

mingus.core.keys.get_key_signature_accidentals(key=C)

Return the list of accidentals present into the key signature.

---

mingus.core.keys.get_notes(key=C)

Return an ordered list of the notes in this natural key.

Examples:

>>> get_notes('F')
['F', 'G', 'A', 'Bb', 'C', 'D', 'E']
>>> get_notes('c')
['C', 'D', 'Eb', 'F', 'G', 'Ab', 'Bb']

---

mingus.core.keys.is_valid_key(key)

Return True if key is in a recognized format. False if not.

---

mingus.core.keys.relative_major(key)

Return the relative major of a minor key.

Example:

>>> relative_major('a')
'C'

---

mingus.core.keys.relative_minor(key)
