JFugue简介

​JFugue 是一个开放源代码编程库，它允许人们使用 Java 编程语言来编程音乐，而无需 MIDI 的复杂性。它由 David Koelle 于 2002 年首次发布。当前版本是 JFugue 5.0，已于 2015 年 3 月发布。Brian Eubanks 将 JFugue 描述为 “对于需要快速便捷地播放音乐或生成 MIDI 文件的应用程序有用”。JFugue 是根据 Apache License 发布的免费软件。 ​

HelloJFugue

public class HelloMusic {public static void main(String[] args) {Player player = new Player();player.play("C D E F G A B");}
}

运行程序即可听到电脑发出的音乐声

注：下面内容可能涉及到一些音乐基本知识和JFugue的语法问题，这里我在网上找了一篇比较不错的博客，供大家参考学习，JFugue4.0 中文说明_鼠晓的博客-CSDN博客

这里是JFugue4.0中文说明，引入的版本是5.0，我都试过，仅在一些类库上有一些升级。

演奏千千阙歌

下面是我从某宝购买的《千千阙歌》的简谱【五线谱入门门槛是在是高】

刚开始学习的我也是对照着语法一个音符一个音符手敲的，发现太费力气了，例如下面这样。

于是我在音符规则上包了一层属于自己的、比较好理解的数字规则【还是废力，但比以前好点】。

由原来的手敲字母变为了下面这样，手敲数字 doge【纯属实现功能，没关注代码整体设计方面】

有两份文件是因为简谱中将谱分为了左右手两个谱，对应简谱里就是两行。

0-5-4 可以理解为用 "-" 号将音符-音调-时长分隔开，"_" 代表连音符

主程序运行

    public static void main(String[] args) {String song1 = CreateMusicApp.outputMusic("E:\\IdeaCode\\Shuttle_Music\\src\\main\\resources\\qqqg\\temp.txt");String song2 = CreateMusicApp.outputMusic("E:\\IdeaCode\\Shuttle_Music\\src\\main\\resources\\qqqg\\temp2.txt");System.out.println(song1);System.out.println();System.out.println(song2);Player player = new Player();Pattern music = new Pattern();Pattern pattern1 = new Pattern("T60 KEY:C V0 " + song1);Pattern pattern2 = new Pattern("T60 KEY:C V1 " + song2);music.add(pattern1);music.add(pattern2);player.play(music);}

运行程序即可享受到动听的音乐~

如果想保存到本地可以调用以下方法保存为 mid 格式文件

MidiFileManager.savePatternToMidi(pattern, new File("千千阙歌.mid"));
