Mr. Bob Fulton used to call the music frequencies "EPI"s which he said stood for "events per instant". Not bad at all description, is it ?? He wrote a paper on it.
He measured a Trumpet at 80KHZ, and a Harp at 110 KHZ, using conventional terms.
Bob was using his own 2 GHZ TEK scope back in the early 1980s, to view audio.
