"The inevitable note"

Wynton Marsalis, talking about Horace Silver, said his compositions had those "inevitable notes" -- you know, the notes that just sound perfect. What a great description! There are lots of great tunes, but the really great ones have those surprising notes that are unexpected but inevitable. "Duke Ellington's 'Prelude to a Kiss' is nothing but inevitable note," Marsalis said.
Got that right!
