Create a Chord

>>> from pychord import Chord
>>> c = Chord("Am7")
>>> c
<Chord: Am7>
>>> c.info()
"""
Am7
root=A
quality=m7
appended=[]
on=None
"""

Transpose a Chord

>>> c.transpose(3)
>>> c
<Chord: Cm7/Bb>

Get component notes

>>> c = Chord("Am7")
>>> c.components()
['A', 'C', 'E', 'G']

Compare Chords

>>> Chord("C") == Chord("D")
False
>>> Chord("C#") == Chord("Db")
True
>>> c = Chord("C")
>>> c.transpose(2)
>>> c == Chord("D")
True

Find Chords

>>> from pychord import note_to_chord
>>> note_to_chord(["C", "E", "G"])
[<Chord: C>]
>>> note_to_chord(["F#", "A", "C", "D"])
[<Chord: D7/F#>]
>>> note_to_chord(["F", "G", "C"])
[<Chord: Fsus2>, <Chord: Csus4/F>]

Create and handle chord progressions

>>> from pychord import ChordProgression
>>> cp = ChordProgression(["C", "G/B", "Am"])
>>> cp
<ChordProgression: C | G/B | Am>

>>> cp.append("Em/G")
>>> cp
<ChordProgression: C | G/B | Am | Em/G>

>>> cp.transpose(+3)
>>> cp
<ChordProgression: Eb | Bb/D | Cm | Gm/Bb>

>>> cp[1]
<Chord: Bb/D>
