In this journey (obsession) of historic banjo playing, I have turned to reading all of the period literature on the subject that I could find. An observation I made is that it seems most banjoists had a version of "Home, Sweet Home with Tremolo." I had read the instructions for how to play it, listened to Ossman and Eps, but really did not give it much mind.
Then, from Trapdoor's recommendation, I bought Douglas Back's The Banjo Goes Highbrow (if you don't have this get it now). It is incredible, I was riveted. When I got to "Variations on Massa's In The Cold Cold Ground," the hair stood up on the back of my neck (Mr. Back, I would love a copy of your arrangement, though I don't think I could do it justice). My skin crawled. I must have listened to it a hundred times.
I had to learn tremolo. I read Stewart's and Converse's instructions again. I watched classical guitarists play with multiple fingers, it was not the same sound.
My biggest concern was repetitive movement injuries. I did some research on this. It seems that CTS may not even be caused by movement. I also found a correlation between the injuries and sedimentary lifestyles. I just added more forearm exercises and stretches to my workout regiment (this all may be my youthful ignorance).
Other then that, I added Converse's tremolo exercises to my practice sessions, and I am slowly getting there. I am not rushing anything.
Sorry it this sounds a little crazy. I do feel that way when it comes to our instrument.
