MIDI 音符代码是用于表示音符的数字系统，范围从0到127，对应不同的音高和八度。具体如下：
 
<ol>
<li>
音符编号：每个音符对应一个唯一的编号，例如：
<ul>
<li>C4（中央C）的编号为60。</li>
<li>C5的编号为72。</li>
</ul>
</li>
<li>
音高与编号：
<ul>
<li>编号0对应C-1（最低音）。</li>
<li>编号127对应G9（最高音）。</li>
</ul>
</li>
<li>
八度划分：
<ul>
<li>每增加12，编号提高一个八度。例如，C4为60，C5为72。</li>
</ul>
</li>
<li>
半音关系：
<ul>
<li>相邻编号相差一个半音。例如，C4为60，C#4/Db4为61。</li>
</ul>
</li>
<li>
常用音符示例：
<ul>
<li>C4: 60</li>
<li>D4: 62</li>
<li>E4: 64</li>
<li>F4: 65</li>
<li>G4: 67</li>
<li>A4: 69</li>
<li>B4: 71</li>
<li>C5: 72</li>
</ul>
</li>
<li>
应用：
<ul>
<li>MIDI音符代码用于音乐软件、硬件和数字乐器中，控制音符的播放。</li>
</ul>
</li>
</ol>
