A on Mandolin: 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.
Between chopping one number and chopping the next there is a beat and a half of nothing written down, and what goes in it is a fill drawn from here rather than from the page.
