## What it is
Musicpy is a Python library and music programming language for writing music with concise, human-readable syntax built on a fully computerized music theory system. It can generate music, perform advanced music theory analysis and operations, and read/write MIDI and MusicXML files.

## Use cases
- write music with code using concise syntax
- generate music algorithmically from music theory rules
- analyze MIDI files with music theory logic
- convert between musicpy data structures and MIDI files
- read and write musicxml files
- build AI music generation experiments in Python

## When to choose
- you want to compose or algorithmically generate music in Python
- you need programmatic music theory analysis of MIDI files
- you want a human-readable music DSL fully compatible with Python

## When to avoid
- you need audio production or DAW-style editing rather than symbolic music
- you have no music theory background and want a purely visual composition tool
- you need real-time audio synthesis out of the box

## Facets
- artifact type: library
- maturity: active
- function: programming-language, parser, sdk
- domain: audio, developer-tools
- platform: python, cross-platform
- tags: music-theory, midi, music-programming, algorithmic-composition, music-analysis, musicxml, algorithms
