🟢transpose_chords(sheet, semitones, from_key, to_key, capo_fret, ...)
Use this when you want to transpose chords or change the key of a song. Accepts a sheet up to 12,000 characters, chords above lyrics or ChordPro brackets; choose semitones -11 to +11, from_key with to_key, or capo_fret 0 to 9. Returns key change, chord mapping, widget sheet and a Latin-only Courier PDF. Chord names only; does not process audio, tablature or staff notation. Key estimates can be wrong for songs that change key.

}🟢find_capo_options(key, chords)
Use this when you want a capo chart or capo calculator for a sounding key or chord list. Returns frets 0 to 9, the shapes to play and easy open chord counts. Supply one key or 1 to 100 chord names, each up to 80 characters. Does not process audio, tablature or staff notation; ease counts chord names, not fingering variations.

}🟢show_chord_sheet(sheet, from_key, title, spelling)
Use this when you want a live chord sheet with -1 and +1 semitone controls. Accepts 1 to 12,000 characters in chord-line or ChordPro format; controls call transpose_chords. Shows the original key and chord counts plus a Latin-only Courier PDF. Chord names only; does not process audio, tablature or staff notation. Key estimates can be wrong for songs that change key.
