The New Imperial Method by C.L. Staats is a one volume method book with a fingering chart by Austin J. McDowell. The method book includes basics of posture, embouchure, and finger position as well as making the first sound on the clarinet. The book then delves deeper into major and minor scales, followed by articulation studies. The last quarter of the book is reserved for Etudes written by Hyacinthe Klosé and Cyrille Rose.
