I will put alink up to my playing of an irish polka,using chords on a 10 hole hamonica not in paddy richter tuning.
it illusrates how chords do suit SOME tunes,it also shows a different style not necessarily better[thats subjective]it shows how on occasions a chordal approach does work.

This is not a competition,hopefully just a demonstration of how several styles can work
