This volume of exercises is devoted to changes of position and preparatory studies for scales over three octaves (in 3rds, 6ths, octaves and 10ths). Our new edition is based essentially on the original print, issued in the early 20th century, and on sources from Ševcík’s posthumous papers. The editor, Jaroslav Foltýn, is professor of violin at Prague Conservatory, a position once held by Ševcík himself.
