In 1942, Rich and Henry Adler wrote "Buddy Rich's Modern Interpretation of Snare Drum Rudiments", which is regarded as one of the more popular snare drum rudiment books. Adler met Rich through a former student. Adler said, "The kid told me he played better than Krupa. Buddy was only in his teens at the time and his friend was my first pupil. Buddy played and I watched his hands. Well, he knocked me right out. He did everything I wanted to do, and he did it with such ease. When I met his folks, I asked them who his teacher was. 'He never studied', they told me. That made me feel very good. I realized that it was something physical, not only mental, that you had to have." Adler denied the rumor that he taught Rich how to play. "Sure, he studied with me, but he didn't come to me to learn how to hold the drumsticks. I set out to teach Buddy to read. He'd take six lessons, go on the road for six weeks and come back. He didn't practice. He couldn't, because wherever the guy went, he was followed around by admiring drummers. He didn't have time to practice...Tommy Dorsey wanted Buddy to write a book and he told him to get in touch with me. I did the book and Tommy wrote the foreword. Technically, I was Buddy's teacher, but I came along after he had already acquired his technique."
