# chorder-py 0.1.2 Fork of chorder with drum fixes. ## Installation `chorder-py` is a chord detection and reharmonize tool for `.mid` files. You can download `chorder-py` using pip: ```shell pip install chorder-py ``` To check if `chorder-py` is successfully installed, type `python` in the terminal, and do the following: ```python >>> from chorder import Chord >>> Chord() Chord(root_pc=None, quality=None, bass_pc=None) ``` ## Documentation ### Chord The `Chord` class is the basic building block for the whole chorder package. A `Chord` instance has four attributes, including: - `root_pc` - the pitch class of a chord's root note - is an integer ranging from 0 to 11 - `quality`, the quality of a chord (the complete list of quality) - the quality of a chord - is a string - the complete list of qualities covered in `chorder` can be found at `Chord.standard_qualities` - `bass_pc` - the pitch class of a chord's bass note - is an integer ranging from 0 to 11 - `scale` - the scale of the chord - is a list of strings representing the note names of each pitch class from 0 to 11 - if a scale is not specified, a default scale is used, which is in `Chord.default_scale` #### `Chord.__init__(self, args=None, scale=None)` ##### Parameters - `args`: `None` or `str` or `tuple`, optional - `None`: implies constructing an empty chord - `str`: a chord symbol, such as `'Bbmaj7'` - `tuple`: a tuple consisting of `(root_pc, quality, bass_pc) - `scale`: `list`, optional - specify the scale the chord uses - will use `Chord.default_scale` if left as `None` #### `Chord.root(self)` Returns the root note name of a chord based on the chord's scale. #### `Chord.bass(self)` Returns the bass note name of a chord based on the chord's scale. #### `Chord.bass(self)` Returns if any attributes of a chord is `None`. This can help filtering empty chords. #### `Chord.transpose(self, key)` Transposes a chord to C-based relative chord. For example, `Chord('Bb7').transpose(3)` should return `Chord('G7')`. ##### Parameters - `key`: `int` - the pitch class of the key - ranges from 0 to 11 ### DeChorder `DeChorder` is a class that consists of static methods related to chord recognition. To utilize this class, the midi information has to be in the form of [miditoolkit](https://github.com/YatingMusic/miditoolkit) objects. #### `Dechorder.get_bass_pc(notes, start=0, end=1e7)` Returns the pitch class of bass note among the notes between the time range of `start` and `end`. ##### Parameters - `notes`: list - the group of notes - notes are in the form of `miditoolkit.midi.containers.Note` - `start`: int - the start tick of the notes to be considered - set it to `notes[0].start` for now, as this feature will later be updated - `end`: int - the end tick of the notes to be considered - set it to `notes[-1].end` for now, as this feature will later be updated #### `Dechorder.get_chord_quality(notes, start=0, end=1e7, consider_bass=False)` Returns the chord among the notes between the time range of `start` and `end`. ##### Parameters - `notes`: list - the group of notes - notes are in the form of `miditoolkit.midi.containers.Note` - `start`: int - the start tick of the notes to be considered - set it to `notes[0].start` for now, as this feature will later be updated - `end`: int - the end tick of the notes to be considered - set it to `notes[-1].end` for now, as this feature will later be updated - `consider_bass`: `bool - decreases the likelihood of chords with non-chord tones as bass to be chosen as the answer #### `Dechorder.dechord(midi_obj, scale=None)` Returns a list of chords by beat. ##### Parameters - `midi_obj`: `miditoolkit.midi.parser.MidiFile` - the midi object to extract chord symbols from - `scale`: `list` - the list of note names for each pitch class - must be a list of strings
