A on Fiddle: What the Chart Leaves Out

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.

This reader plays almost nothing the chart actually wrote: the numbers give the harmony and the line over the top of them is assembled, bar by bar, out of the notes on this page.
