PyTheory: Music Theory for Humans

pytheory is a Python library that simplifies working with music theory concepts. It provides a simple and intuitive interface for representing musical elements such as notes, scales, chords, and intervals, making it easier to work with music theory in Python.

Features

• Note Representation: PyTheory allows you to represent musical notes using the standard Western notation (A, Bb, C#, etc.), enabling you to work with notes in different formats.
• Scale Generation: The library provides functions for generating scales based on different modes, such as major, minor, pentatonic, and blues scales, allowing you to explore different musical scales.
• Chord Construction: PyTheory supports constructing chords from notes, intervals, or scale degrees, making it easy to create and analyze chords in different keys.
• Interval Calculation: The library allows you to calculate intervals between notes, enabling you to determine the distance between two pitches in a musical context.

This project is highly experimental, and is more of a thought exercise than a practical library. It aims to explore how music theory concepts can be represented and manipulated using Python, and to provide a foundation for further research and development in this area.

Installation

You can install pytheory using pip:

$ pip install pytheory
