BY THE NUMBERS: NASHVILLE NUMBER CONVERTER

Translate chord charts into Nashville numbers, transpose charts into new keys, or turn Nashville numbers back into playable chords.

Turn chords into numbers. Turn numbers back into chords.

Paste a chart with chords, form labels, lyrics, rehearsal notes, or performance cues. The converter changes the chords and leaves the words alone.

Use plain text cues: diamond(C), choke(G7), or push(F). The display turns those cues into chart symbols. Use uppercase root letters for chords so lyrics stay lyrics.

Symbol Legend

Nashville charts are built for fast reading. Numbers show scale degrees. Symbols show chord quality, bass motion, pushes, holds, cutoffs, and performance cues. The converter preserves words and renders cue text as chart notation.

Arabic numbers: Nashville charts use 1, 2, 3, 4, 5, 6, and 7 instead of Roman numerals.
Minor indicator: Minor chords must be marked with m or −. A plain 6 means major; 6m means minor.
Seventh chords: Type 57, 1maj7, or 6m7. The display raises the 7 automatically.
Slash chords: Type G7/B in chord mode or 57/7 in number mode.
Cue syntax: Type diamond(C), choke(G7), or push(F). The buttons can wrap selected text automatically.
Words stay words: Lyrics, section labels, and rehearsal notes are preserved while chord symbols convert.
