# MusicKit
MusicKit is a framework and DSL for creating, analyzing, and transforming music in Swift.
### Examples
**Functional harmony**
```swift
let C5 = Pitch(midi: 72)
let neapolitan = Major.bII
print(neapolitan(C5)) // [C♯5, E♯5, G♯5]
let G4 = Chroma.G*4
let plagalCadence = [Major.IV, Major.I]
print(plagalCadence * G4) // [[C5, E5, G5], [G4, B4, D5]]
let V7ofV = HarmonicFunction.create(Scale.Major, degree: 5, chord: Major.V7)
print(V7ofV(C5)) // [D6, F♯6, A6, C7]
```
**Chord recognition**
```swift
let pitchSet: PitchSet = [Chroma.B*0, Chroma.Cs*2, Chroma.F*3, Chroma.G*4]
print(Chord.name(pitchSet)) // G7♭5/B
let descriptor = Chord.descriptor(pitchSet)
print(descriptor) // root: G, quality: 7♭5, bass: B
```
**MIDI I/O**
```swift
let midi = MIDI(name: "WholetoneClusters")
midi.noteHandler = { messages in
if let first = messages.first {
midi.send([first, first.transpose(2), first.transpose(3)])
}
}
```
