Piano arrangement on hand-punched paper. A dynamic music roll of Finger Breaker composed by Jelly Roll Morton, AS PLAYED BY Jelly Roll Morton. Also known as Finger Buster and often confused with Willie Lion Smith's Finger Buster. Note: Music rolls or piano rolls were almost never played or recorded by a pianist. Even when the artist was part of the process, arrangers, some skilled, some not, edited the rolls heavily and limited by factory rules and equipment. Performed and interpreted on my player piano from the 1920s.
