How to Recognize and Count Chord Symbols Imported as Lyrics in MusicXML Using Music21?

[XuhongQiu]

Hi, I'm looking to understand how to use Music21 to identify chord symbols that have already been imported as lyrics in a MusicXML file. I used MuseScore to create a monophonic melody along with corresponding chords and now hope to use Music21 to recognize these chord symbols (especially non-harmonic chords) and tally them. Unfortunately, I've only found methods for analyzing and importing Roman numeral annotations and analyzing lyrics in the user manual. Is there anyone who could offer me some inspiration?

are you thinking of something like?

for el in s[note.GeneralNote]:
    if el.lyric:
        # probably do a try/except here
        cs = harmony.ChordSymbol(el.lyric)
        m = el.activeSite
        m.insert(el.offset, cs)
