Part of Ellen Ballon fonds
File contains a piano technique book used by Ellen Ballon while she was studying with Alberto Jonas in New York. Each page includes printed technical excercises and blank staff lines with some additions handwritten in pencil, presumably by Jonas or Ballon. The book includes a repertoire list of pieces Ballon performed in 1918-1919.
