D# on Resonator: the Numbers It Answers To
62 qualities on one root, each with the number that calls it.
Everything rooted on D#, 62 qualities in 10 families. A chart will ask for three or four of them by number and leave the rest to the record, but the root is the part the number pins down, so this is the page a reader lands on first.
D# answers to the 1, 2, 3, 4, 5, 6 and the 7 depending on what got called: it is a plain number in 7 of the twelve keys and needs an accidental in the other 5.
A resonator player reads a number as a place to stop the bar — the strings are already a chord, so what the digit changes is not the grip but where along the neck the bar has to be sitting when the bar of music starts. The open strings already spell a chord, so a number is answered with a position rather than a grip, and the whole reading job is arriving at the right one square on the beat.
