One of the principles of music notation publishing is economy. Publish as much music as possible in the smallest amount of space. This principle was driven by physical constraints of material and human labor. It led to the use of repeat signs, target signs of several types, measure repeat signs, and more.
When I was putting together my book 43 Fiddle Tunes in Tab, I used these concepts to draw maps of tabs that were sometimes hard to follow. It gives me great satisfaction to straighten out some of these twisty pathways on this blog.
One such is the fiddle tab chart I made for Swallowtail Jig. There is one area in the B part that has stumped students repeatedly, (forgive the pun). In the chart below it is rewritten more intuitively.
