吉他歌曲建構器怎麼用
這個頁面是一間小型編曲室。你選一組和弦進行，決定每個和弦持續多久，設好刷弦型與速度，再用與模擬器相同的木吉他音色聽回來。下面的順序能最快做出一首彈得出來的歌。
先定調與三、四個和弦
先選調，再選和弦：同一個調裡的和弦聽起來才像一家人。G–D–Em–C、C–G–Am–F 和 Em–C–G–D 涵蓋了流行與民謠的一大部分。曲庫有 31 個和弦，分屬大、小、七、掛留與加音幾類，每個都能在加入前先試聽，所以換和弦是聽出來的，不是猜出來的。
給每個和弦一小節、兩小節或四小節
在目前速度下，一小節是四拍。一個和弦一小節節奏明快、往前推；兩小節是流行歌常見的選擇，留出呼吸；四小節則能讓和弦在旋律或長音下方持續。這個設定既作用於整段進行，也能只作用於某個和弦，所以主歌與副歌可以用不同的節奏密度。
把刷弦寫成符號序列
刷弦型就是一串符號：向下箭頭是下刷，向上箭頭是上刷，手掌符號是悶音——弦被止住而不是繼續鳴響，雷鬼、放克與大多數流行副歌的律動就來自這裡。先學「Basic」與「Down-Up」；「Pop」會在反拍加悶音，「Slow」把刷弦拉開。「Custom」裡可以增刪符號做自己的型，做好的型每小節重複一次。
決定右手做什麼
「Full Strum」同時刷過六根弦，就是多數人想像中的節奏吉他聲。「Down / Up」交替上下刷，聽感更輕更快。「Arpeggio」把和弦逐弦滾出來，是民謠與指彈歌的聲音。「Individual」一次只撥一根弦，可以讓你還沒練熟的旋律下面鋪一個安靜的和弦。
旋律放在最後，疊在上面
旋律音域從 C3 到 G5，約三個八度。用選擇器逐個加音，或從旋律曲庫載入一段，只留下合用的音。屬於和弦的音聽起來安定，和弦之間那些音（例如 C 和弦上方的 D）會把旋律往前推。先把句子哼出來，再去選擇器裡找這些音——一個一個試要慢得多。
設速度、試聽，然後錄音
90 BPM 是穩妥的起點；和弦換法還生疏時降到 60 或 70。打開循環跟著彈，直到不用看也能換和弦。錄音走的是與模擬器相同的 Karplus–Strong 吉他引擎，所以下載的 WAV 就是剛剛聽到的聲音；範圍選擇器決定錄目前這行、選取的行或全部。
儲存行，把循環變成一首歌
儲存的行是目前進行連同速度與刷弦型的快照。存下主歌，清空序列，做出副歌再存一條，然後在已儲存行的面板按「Play all」，它們就會依序播放。兩個循環加一次重複，已經是歌曲結構了。
第一次可以這樣：G–D–Em–C，90 BPM，一個和弦一小節，「Basic」刷弦。每次只改一樣——先刷弦型，再演奏風格，最後速度——這樣才聽得出每一樣在做什麼。
常見問題
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.
