This dance classic presents a complete beginning course in classical ballet. The founder of this method, Enrico Cecchetti (1850–1928), performed and taught in Russia and with Diaghilev's troupe. By elaborating on a logical progression of exercises, Cecchetti provided dance with an unprecedented unity — balancing the adagio and allegro, re-establishing the notion of "legato," strengthening the arabesque, and developing the exercise of the pliés. Cyril W. Beaumont, a distinguished writer on ballet, has codified Cecchetti's program of study with the assistance of one of Cecchetti's star pupils, Stanislas Idzikowski, and with the approval of Cecchetti himself.
