Music Theory Library for Java and Android apps

Music Theory

Introduction

Java music theory library inspired by the Music Theory Library for Swift OS X and iOS apps.. 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:

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

Step 2. Add the dependency

	dependencies {
	        compile 'com.github.Andy671:MusicTheory:v0.6.4'
	}

Usage

	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]}
