George Lawrence Stone’s Stick Control for the Snare Drummer first appeared in 1935. With a terse two-page introduction followed by a mere 21 pages of what he called “practice rhythms”, Stone unleashed a new and powerful method of technical development for all styles of drumming. The “HOW TO PRACTICE” page alone is worth the price of the book, and, although he never uses the word exercise, he explains clearly how to use his “conditioners” in a progressive and ambidextrous calisthenic routine, leading to speed, endurance, power and precision.
