Nashville Number Converter
Transpose a simple chord progression through scale-degree notation while keeping chord suffixes.
A QUICK WALKTHROUGH
How to use this tool
- Choose chord-to-number or number-to-chord mode and a major key.
- Enter chord symbols or Nashville tokens separated by spaces, commas, bars, or new lines.
- Convert locally, review unsupported tokens, and copy the result.
Supported symbols
Chord roots A–G may use one # or b, followed by a suffix such as m, 7, maj7, sus4, or dim. Nashville tokens use an optional b or #, a degree 1–7, and a suffix. Slash chords and key changes inside one progression are not interpreted.
Major-key spelling
The converter uses the seven degrees of the selected major key. Output chord names prefer flats for flat keys and sharps for other keys; enharmonic spelling may differ from a published chart.
Notation aid, not harmonic analysis
Suffixes are preserved as text. The tool does not infer chord quality, inversions, secondary dominants, modes, timing, or whether a progression is musically correct.
