# 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)])

    }

}

```
