Development & Maintenance of Techniques for All Brass Instruments (Treble Clef)

John Haynie’s Development and Maintenance of Techniques for All Brass Instruments in Treble Clef is a legendary method book known simply as the “D&M Book” to generations of brass players. Designed as a comprehensive routine for the daily preservation and advancement of trumpet technique, this collection offers a systematic series of exercises that cover every essential technical aspect—tone, flexibility, articulation, range, scales, and endurance—across all twelve keys. Inspired by Ernest S. Williams’s The Secret of Technique Preservation, Haynie expanded upon that model to create a more complete, brass-specific approach. His insights into breath control, tone production, and consistent fundamentals are woven throughout the material, including his signature emphasis on efficient air use: “Let us concentrate on getting rid of the air, and then taking air in will be both natural and effective.” As Frank Gabriel Campos, one of Haynie’s students, recalls: “My late teacher, John James Haynie, continually searched for the most efficient way to develop and maintain one’s technique on the trumpet through specific daily exercises and drills. Haynie’s Development and Maintenance of Techniques, nicknamed the ‘D&M book,’ was our technique bible at the University of North Texas. We were tested on this material each semester, and that work left a lasting impression on me. The skills I developed preparing for Mr. Haynie’s technique exams have served me well.” Ideal for advanced high school students, university studio players, and professionals, this book remains one of the most effective tools for developing lasting technique and consistent brass playing. It is as relevant today as it was when first published and continues to be a staple in collegiate brass programs worldwide. Check samples to the left then grab an immediate PDF download above. Note: This book is very similar in content to Haynie’s How to Play High Notes, Low Notes, and All Those In Between. Both include nearly identical daily routines and technical studies. However, this edition features cleaner engraving, a better layout, and superior readability—making this the clear choice between the two.
