鋼琴歌曲建構器怎麼用
鋼琴建構器把工作分給兩隻手：下面彈和弦，上面彈旋律。曲庫裡的每個和弦都能先用再放，做好的編曲會用與鍵盤頁相同的鋼琴音色播放。
挑一段聽得出來的進行
曲庫有 96 個和弦：十二個根音，分別配大、小、七、大七、掛留、減與增。先選一個調，再從裡面取四個和弦——C–G–Am–F、Am–F–C–G、C–Am–Dm–G 都經得起反覆彈。依你想聽的順序加入，拖曳可以重排；這個順序就是作曲本身。
定好每個和弦佔幾小節
每個和弦一小節、兩小節或四小節，每小節四拍。一小節讓音樂保持流動，兩小節是流行與搖滾的常見感覺，四小節給句子留出落點。因為這個設定能作用於整段進行，也能只看某個和弦，八小節的主歌與四小節的副歌可以共處同一個專案。
替左手選一種型
「Block」把和弦音一起彈，是最樸素的伴奏，也是第一個該學的。「Waltz」在低音上疊兩個輕和弦，是 3/4 的搖擺感；「Slow」把和弦拉長，適合抒情與氛圍；「Fast」在需要推進力時重複短和弦。「Arpeggio」把和弦拆成單音，是多數流行主歌的聲音。
旋律放在中央 C 之上
旋律選擇器從 C3 到 G5。右手的旋律大多落在 C4 到 C5 之間，偶爾更高一些；把線留在這個範圍，下面的和弦才聽得清。強拍上用和弦音，中間用連結音，所以順著穩定進行級進的旋律聽起來像為它而寫。也可以從旋律曲庫載入一段當作起點。
速度、循環、錄音
四拍一小節、90 BPM 是常見的練習速度；減半是乾淨學會新和弦連接最快的辦法。打開循環練習，然後錄目前這行、選取的行或全部，並把這一條匯出成 WAV。播放與匯出都走共用的鋼琴引擎，檔案的聽感與剛才一致。
每個段落存成一條行
儲存的行會把進行、速度與風格一起留住：存主歌，清空序列，做副歌，再存一條，按「Play all」就會依序播放。這樣就能不在紙上排出整套編曲——前奏、主歌、副歌、主歌、副歌、結尾。
照建構器的排布順序練：先只聽和弦，再只聽旋律，最後用慢速合在一起。如果某個和弦換不過去，第一個該改的設定是小節長度。
常見問題
Work down the numbered steps on the page. Add chords from the Chord Library (or the Add Chord dropdown) to build your sequence, optionally add a melody in step 3, pick a playing style such as Block, Arpeggio or Waltz in step 4, then set your tempo and chord duration in the right-hand panel and press Play Progression to hear the whole arrangement.
The chord sequence is your accompaniment: each chip is one chord held for the number of bars you choose, and it is played with the style you selected. The melody is the tune that plays on top of those chords. You can add melody notes one at a time with the note picker, generate a random melody, or load a ready-made tune from the Melody Library. Both parts play together during preview.
Open the Song Library panel on the right and click any song, for example Twinkle Twinkle Little Star. The builder loads that song's tempo, fills the chord sequence with a matching progression for its key, and loads the song's actual melody notes so the tune plays correctly over the chords. You can then edit any part of it and make it your own.
Yes. Tempo is set in BPM in the Song Settings card, and Duration sets how many bars each chord lasts (1, 2 or 4). Choose Whole Progression to apply one playing style everywhere, or switch to Customize Per Chord to give each chord in your sequence its own style.
Press Record in the Actions card, then play your progression. When you stop recording you can play the take back in the browser and use the Download button to save the audio file to your device. Recording captures the same audio you hear, including both the chords and the melody.
