One of the more interesting questions asked of the panel was:
"Who has been a major influence on your career"?
My answer was Rob Dickins who told me "Don't send me songs with triads".
"I want those Capek chords"

Those 'Capek chords' more often than not cannot be notated. They are my 'thing'.
Identifying your niche is the best advice I can give a developing songwriter.
Sometimes three chords and the fake truth won't get you there.
