A# on Upright Bass: What the Chart Leaves Out
24 types on one root, for the space between two bars.
Every scale type this site maps, rooted on A# and laid onto this reader. A chart is silent about all of them by design — it prints the harmony a player cannot guess and trusts the room for the rest — so this is the half of the page the numbers deliberately leave blank.
The walk from one number to the next has further to travel on this instrument, so the notes it passes through are chosen for the distance as much as for the harmony.
