Overview

Rust Music Theory is used to procedurally utilize music theory notions like Note, Chord, Scale, Interval and more. The main purpose of this library is to let music theory be used in other programs and produce music/audio in a programmatic way.

Usage as a Library

Add rust-music-theory as a dependency in your Cargo.toml. toml [dependencies] rust_music_theory = "0.1"

After installing the dependencies, you can use the library as follows. ```rust extern crate rustmusictheory as rmt; use rmt::note::{Note, Notes, PitchClass}; use rmt::scale::{Scale, ScaleType, Mode}; use rmt::chord::{Chord, Number as ChordNumber, Quality as ChordQuality};

// to create a Note, specify a pitch class and an octave; let note = Note::new(PitchClass::As, 4);

// Scale Example; let scale = Scale::new( ScaleType::Diatonic, // scale type PitchClass::C, // tonic 4, // octave Some(Mode::Ionian), // scale mode ).unwrap();

// returns a Vector of the Notes of the scale let scale_notes = scale.notes();

// Chord Example; let chord = Chord::new(PitchClass::C, ChordQuality::Major, ChordNumber::Triad);

// returns a Vector of the Notes of the chord let chord_notes = chord.notes();

```

This is the simplest form of the usage. For detailed examples, please see the tests folder.

Usage as an Executable

The binary is implemented as a regex parser cli that returns the notes of the given scale/chord. To quickly build and run the executable locally;
