使用方式
先完成一次順手的操作
- 選擇樂器(吉他/烏克麗麗/鋼琴),再挑根音與和弦性質,指板立刻亮出指型
- 也可以反過來:直接點指板上的弦格,下方即時顯示和弦名稱與組成音
- 每次點擊都會發聲;右上角靜音鍵可關閉音效,不影響任何視覺資訊
彈得出來的和弦圖:選和弦看指型,或反過來點弦命名 — 吉他、烏克麗麗、鋼琴通用 Pick a chord to see its fingering — or tap the diagram to name what you play. Guitar, ukulele, and piano.
這個工具支援兩種方向:正向查詢(選根音與和弦性質 → 指板亮出指型)與反向命名(直接點指板上的弦格 → 工具即時把音組解析為和弦名稱)。音名(C D E)為國際通用,所以語言切換只影響標籤,不影響圖形本身。
如何看懂和弦圖:○ 代表空弦(不按),✕ 代表悶音(不彈),指格裡的數字(1–4)代表手指編號。標示「x-3-2-0-3-0」的格式依序列出第六到第一弦的按弦位置,是吉他手最常見的簡縮寫法。當和弦沒有常用的開放把位時,工具會產生可移動的封閉指型(barre),並用虛線框提示「同一形狀可以沿指板平移」。
目前支援吉他(標準調弦 EADGBE)、烏克麗麗(標準 GCEA)與鋼琴,涵蓋 major、minor、7、maj7、m7、m7b5、add9、sus2、sus4、dim、aug 共 11 種和弦性質。音名可用右上角的 ♯/♭ 按鈕在升號與降號之間切換顯示(單純切換顯示寫法,不影響指型)。若點選的音組無法對應到支援的和弦,會顯示「未知指型」而非猜測一個錯誤名稱。
This tool works in both directions: forward lookup (select root + quality → fingering appears on the diagram) and reverse naming (tap the frets or piano keys → the tool resolves the pitch set to a chord name live). Note names (C D E) are universal, so language switching only affects labels — not the diagram itself.
Reading a chord diagram: ○ means open string (play open), ✕ means muted (don't play), numbers (1–4) inside dots indicate finger positions. The notation "x-3-2-0-3-0" lists fret positions for strings 6 through 1, the most common shorthand for guitarists. When no common open voicing exists, the tool generates a movable barre shape and shows a dashed outline to indicate "this shape slides up and down the neck."
Supported instruments: guitar (standard EADGBE), ukulele (standard GCEA), and piano. Supported chord qualities: major, minor, 7, maj7, m7, m7b5, add9, sus2, sus4, dim, aug. Use the ♯/♭ button (top-right) to switch note spelling between sharps and flats (a display switch only — it doesn't change the fingering). If a tapped pitch set doesn't match any supported quality, the tool shows "unknown shape" rather than guessing a wrong name.

常見問題
吉他(標準調弦 EADGBE)、烏克麗麗(標準 GCEA)與鋼琴。所有音名以國際通用的 C D E 表示,語言切換只影響介面標籤。
可以。直接在指板或琴鍵上點選你按的音,工具會即時把音組解析成和弦名稱(例如 C E G D 會顯示 Cadd9)。無法對應到支援和弦時會顯示「未知指型」而不會亂猜。
當某個和弦沒有常用的開放把位時,工具會用可移動的封閉指型(barre)沿指板平移生成,並標示為 movable,同時顯示半透明虛線框,教你把同一形狀移到別的把位。
不需要。所有指型與命名都在你的瀏覽器本機計算,無後端、無帳號、不上傳。

FAQ
Guitar (standard EADGBE), ukulele (standard GCEA), and piano. Note names use the international standard (C D E), so switching language only changes UI labels.
Yes. Tap any frets on the diagram and the chord ribbon resolves the pitch set to a name in real time (e.g. C E G D → Cadd9). Unrecognised sets show 'unknown shape' rather than a wrong name.
When no common open-position voicing exists for a chord, the tool generates a movable barre shape and labels it 'movable'. A dashed outline on the diagram shows that the same shape can slide up and down the neck.
No. All chord lookups and naming happen locally in your browser — no backend, no account, nothing uploaded.
