吉他歌曲构建器怎么用
这个页面是一个小型编曲室。你选一组和弦进行，决定每个和弦持续多久，设好扫弦型和速度，然后用与模拟器相同的原声吉他音色听回来。下面的顺序能最快做出一首可以弹的歌。
先定调和三四个和弦
先选调，再选和弦：同一个调里的和弦听起来才像一家人。G–D–Em–C、C–G–Am–F 和 Em–C–G–D 覆盖了流行与民谣的很大一部分。曲库有 31 个和弦，分属大、小、七、挂留和加音几类，每个都能在加入之前先试听，所以换和弦是听出来的，不是猜出来的。
给每个和弦一小节、两小节或四小节
在当前速度下，一小节是四拍。一个和弦一小节节奏明快、往前推；两小节是流行歌的常见选择，留出呼吸；四小节则能让和弦在旋律或长音下方持续。这个设置既能作用于整段进行，也能只作用于某个和弦，所以主歌和副歌可以用不同的节奏密度。
把扫弦写成符号序列
扫弦型就是一串符号：向下箭头是下扫，向上箭头是上扫，手掌符号是闷音——弦被止住而不是继续鸣响，雷鬼、放克和大多数流行副歌的律动就来自这里。先学“Basic”和“Down-Up”；“Pop”会在反拍加闷音，“Slow”把扫弦拉开。“Custom”里可以增删符号做自己的型，做好的型每小节重复一次。
决定右手做什么
“Full Strum”同时扫过六根弦，就是多数人想象中的节奏吉他声。“Down / Up”交替上下扫，听感更轻更快。“Arpeggio”把和弦逐弦滚出来，是民谣和指弹歌的声音。“Individual”一次只拨一根弦，可以让你还在学的旋律下面铺一个安静的和弦。
旋律放在最后，叠在上面
旋律音域从 C3 到 G5，约三个八度。用选择器逐个加音，或从旋律曲库载入一段，只留下合用的音。属于和弦的音听起来安定，和弦之间那些音（比如 C 和弦上方的 D）会把旋律往前推。先把句子哼出来，再去选择器里找这些音——一个一个试要慢得多。
设速度，试听，然后录音
90 BPM 是稳妥的起点；和弦换法还生疏时降到 60 或 70。打开循环跟着弹，直到不用看也能换和弦。录音走的是与模拟器相同的 Karplus–Strong 吉他引擎，所以下载的 WAV 就是刚刚听到的声音；范围选择器决定录当前行、选中行还是全部。
保存行，把循环变成一首歌
保存的行是当前进行连同速度与扫弦型的快照。存下主歌，清空序列，做出副歌再存一条，然后在已保存行的面板里按“Play all”，它们就会依次播放。两个循环加一次重复，已经是歌曲结构了。
第一次可以这样：G–D–Em–C，90 BPM，一个和弦一小节，“Basic”扫弦。每次只改一样——先扫弦型，再演奏风格，最后速度——这样才能听出每一样在做什么。
常见问题
Add chords to the sequence from the Chord Library, choose a strumming pattern of down, up and mute strokes, set your tempo and how many bars each chord lasts, then press Play Progression. The builder strums each chord for you with realistic string timing so you can hear the whole arrangement before you play it yourself.
The pattern is a repeating series of strokes spread evenly across each chord. Down and up strokes strum the strings in opposite directions, and mute produces a percussive damped hit. Choose Whole Progression to use one pattern throughout, or Customize Per Chord to give individual chords their own strumming pattern.
Yes. Open the Song Library panel, search for a title and click it. The builder loads that song's tempo, builds a chord progression that fits its key, and loads the song's melody so you hear the actual tune strummed over the backing chords. Everything stays fully editable afterwards.
The Chord Library covers major, minor, 7th, sus and add chord families, and you can filter by category or search by name. Each row has a play button that previews the chord on its own, and a plus button that appends it to your sequence, so you can audition a chord before committing it to the song.
Turn on Loop in the preview card so the progression repeats continuously, then start at a slow BPM and play along on a real or virtual guitar. Raise the tempo a few BPM at a time as the chord changes get comfortable. The chord chip that is currently sounding is highlighted, which makes it easy to see the change coming.
