Tone Study for the Lifelong Flutist grew out of Leonard E. Lopatin\'s experiences over a nearly fifty-year career, building on what he found useful from standard pedagogy books and coaching he received in high school, the Manhattan School of Music, and the Juilliard School. Lopatin, best known as the innovative designer of the SquareONE family of flutes, concentrated on making his daily practice time as effective as possible for maintaining the skills that first earned him a seat in the Metropolitan Opera Orchestra. What would be the point of crafting the kind of flutes he wanted to play if he neglected his professional flute playing skills? Divided into 48 large sections, each with twelve sub-sections, these tonal exercises are designed to facilitate the practice of moving smoothly from each note to every other note in the flute\'s range while building (or maintaining) the endurance needed to play for an extended period of time. These exercises are designed to continually challenge players in their lifelong efforts to advance their playing abilities. Flute players will undoubtedly find Tone Study for the Lifelong Flutist a must-have for their pedagogical library. Indeed, players of all woodwind and brass instruments will find that the patterns which fall into their range are great for building the strength and flexibility needed for mastery.

Offermans' famous etude book concerning comtemporary flute techniques, which has been awarded by the Newly Published Music Committee of the National Flute Association, USA in 1993. These studies can help flutists not only to deepen their knowledge about contemporary flute playing, but also to develop breathing, use-of-body and flute-sound in general.
