When I was in college, one of the other
percussionists had perfect (absolute) pitch.
He was primarily a keyboard percussionist
(vibes, xylophone, marimba, etc.). One of
his music theory instructors said that the
student would make an excellent violinist.
The student could pick up almost any available
musical instrument, and play it well, after
exploring the instrument for about a minute.
I'd play a harmonica, and he would tell me the
notes I was playing, the key or keys used,
and even the chords played with their spellings.
in the correct inversions.
I'd pick up a different harmonica of the same
model and type, in a different manufacturer's
key, and he could name the notes, keys and
chords, with correct inversions, on that 2nd
harp. He was amazing.
In contrast, I played a concert in the Kettle
Moraine (Wisconsin) Symphony on 1-24-14.
The featured artist was Corky Siegel on piano
and diabolic harp, and I was playing percussion.
During a rehearsal break, I was improvising
on a Richter blues harp, and he asked me,
"Was that a 9th chord?"
I told him, "I don't know".
Even with a known key, I couldn't name the
pitches or chords that I played.
Today, we know that there is only one
factory-installed 9th chord on a 10-hole
Richter system blues harp: draw holes
2 through 6. It's called a dominant 9th
chord.
