Overview
Converts chord charts to Nashville numbers, in place on the page.
Rundown rewrites a chord chart in place, turning chord symbols into Nashville number degrees. For example, Eb Gm Ab Bb becomes 1 3m 4 5. Open a page with a chord chart, click the toolbar button, and the chart is renumbered where it sits — lyrics, spacing and column alignment untouched. Click again to put the original chords back. Nothing is changed permanently, and nothing is uploaded anywhere. WHAT IT DOES • Detects the key automatically, and shows you its ranked runners-up so you can override it in one click when a song is ambiguous. • Numbers minor songs from the relative major by default, the way session charts are usually written, so a minor song reads 6m-centred. Prefer to number from the minor tonic instead? One toggle, remembered for next time. • Keeps the chart readable: extensions render as proper superscript, so a five chord with a seventh does not come out looking like "fifty-seven". • Handles slash chords, extensions, suspensions and borrowed chords, and spells degrees properly — an F# in C reads #4, while a Gb in C reads b5. • Survives the page's own transpose controls; the numbers stay put. • Copy a renumbered chart and you get readable text, not run-together digits. PRIVACY No accounts, no tracking, no analytics, no servers. The extension stores one setting — how you like minor songs numbered — in your browser. It reads the page only when you click the button, and never sends any page content anywhere.
