Blues guitar instrumental. Interestingly, this piece is always attributed solely to Sylvester Weaver, but on his original January 1924 Okeh release the blues singer Sara Martin (who Weaver did work with) is co-credited and she is as well by ISWC and on the copyright.
Bob Wills recorded a steel guitar version in 1936 that he called "Steel Guitar Rag", and his guitar player, Leon McAuliffe, registered the work as his own, but it's the identical tune just a countrified version of Weaver's blues rag.
