## Introduction

Java music theory library inspired by the [Music Theory Library for Swift OS X and iOS apps.](https://github.com/danielbreves/MusicTheory).

I am still working on it, so it will become better eventually.

Project uses Java 1.7, so you can use it in your Android projects without any problems.

## Installation

Step 1. Add the JitPack repository to your build file

Add it in your root build.gradle at the end of repositories:

```gradle

	allprojects {

		repositories {

			...

			maven { url 'https://jitpack.io' }

		}

	}

```  

Step 2. Add the dependency

```gradle

	dependencies {

	        compile 'com.github.Andy671:MusicTheory:v0.6.4'

	}

```

## Usage

```java

	Note dSharpNote = new Note("D#");

	System.out.println(dSharpNote); // D#4[63]

	dSharpNote = new Note("D#", 5);

	System.out.println(dSharpNote); // D#5[75]

	Chord dSharpm7Chord = dSharpNote.chord("m7");

	System.out.println(dSharpm7Chord); // D#m7 inversion[0] {D#5[75], F#5[78], A#5[82], C#6[85]}

	Scale dSharpScale = dSharpNote.scale("minor");

	System.out.println(dSharpScale); // D# minor scale {D#5[75], E#5[77], F#5[78], G#5[80], A#5[82], B5[83], C#6[85]}

	Key cFlatMajorKey = new Key("Cb", "major");

	System.out.println(cFlatMajorKey); // Cb major key

	Chord thirdFlatDegreeAugChord = cFlatMajorKey.chord("bIII", "aug");

	System.out.println(thirdFlatDegreeAugChord); // Ebbaug inversion[0] {Ebb4[62], Gb4[66], Bb4[70]}

	thirdFlatDegreeAugChord.setPosition(1);

	System.out.println(thirdFlatDegreeAugChord); // Ebbaug inversion[1] {Bb5[82], Ebb4[62], Gb4[66]}

	thirdFlatDegreeAugChord.sort();

	System.out.println(thirdFlatDegreeAugChord); // Ebbaug inversion[1] {Ebb4[62], Gb4[66], Bb5[82]}

```
