Use to create a diagram of all variations of a guitar chord from a given string.
- Python 3.9 or higher
- External library dependencies: scikit-learn, NumPy, matplotlib
Clone or download the code repository. To install the dependencies run:
python -m pip install matplotlib scikit-learn numpy
The main.py provides two convenience functions:
plot_chord_shapes - Plot all possible open chord shapes by providing
a string of a chord name to be displayed and a plot argument of how
different variants should be displayed.
If an integer is provided then only the plot with that integer index will be displayed. If 'all' then all variants will be shown on a large plot. If 'one-by-one' then the script will display plots one by one in the order of the index.
Args:
chord_string (str): A string of chord name
plot (int | str): Value of how to display plot.
If an integer is provided then only the plot with that
integer index will be displayed. If 'all' then all
variants will be shown on a large plot. If 'save-all'
then the script will display plots one by one in the
order of the index.
find_chord_name_from_diagram - Find the name of a chord from finger diagram.
Args:
finger_positions (list[tuple[int, int]]): A list of tuple of finger positions
on a fretboard in the form (string, fret).
open_strings (list[int]): A list of integers of strings that are played open.
muted_strings (list[int]): A list of integers of strings that are muted.
Returns:
str | None: A string of the chord name
