Here's another very 'period' sounding piece, well 1897... Standard drill, A notation duo transposed to C notation, tab included. Doesn't look too hard...I've set the mp3 at a 'Con moto' pace, so it moves along!
I have several 'ordinary' teaching pieces by Jennings and they're all self-published out of Providence, Rhode Island. I don't know much else about him. Joel has posted a copy of his "Practical Banjo School" to the internet archive. I don't know its value re: tutor but it is stuffed with music.
