# Music Theory Library for Swift

A minimal library for Western music theory in pure Swift, defining notes, scales, chords, intervals, progressions and more.

Since no external dependencies are needed, it runs on Linux, macOS and any other platform supporting Swift 5.7+, including the browser with [SwiftWasm](https://github.com/swiftwasm).

## Examples

```swift

// Creating (octaved) notes

Note(.c, 3)             // -> C3

Note(.d.flat, 2)        // -> Db2

// Applying diatonic intervals

Note(.c, 3) + .majorThird // -> E3

Note(.d, 2) + .octave     // -> D3

// Applying chromatic intervals

Note(.f, 2) + .semitone

Note(.g.sharp, 0) + .semitones(3)

// Creating scales

MajorScale(key: Note(.e, 2)).notes       // -> [E2, F#2, G#2, A2, B2, C#3, D#3]

MinorScale(key: Note(.c, 1)).notes       // -> [C1, D1, Eb1, F1, G1, Ab1, Bb1]

MinorBluesScale(key: Note(.g, 0)).notes  // -> [G0, Bb0, C1, Db1, D1, F1]

```

To experiment with the library yourself, simply run `swift run --repl` to open an interactive shell and enter

```swift

import MusicTheory

```
