## Basic Usage

### Create a Chord

```python

>>> c = Chord("Am7")
>>> c
<Chord: Am7>
>>> c.info()
"""
Am7
root=A
quality=m7
appended=[]

<Chord: Cm7/Bb>
```

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

### Find Chords

```python
>>> 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

```python
>>> 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>
```
