Although Bill Keith did a lot to promote banjo tablature, the standard
was pretty much in place when Pete Seeger published his "How to Play the
5-string Banjo." This is not to subtract from or diminish the Keith
contribution(s) one single bit. Earl Scruggs had little, if anything, to
do with tabulature at all. In fact, once, when I was at Earl's house in
1965, I asked him what he called a certain "roll." He told me that he
had never even heard of a roll until Bill Keith showed him all of the
stuff he had written down, and explained what a roll was.
I hope this information proves useful or at least informative to the
trivia collectors.
