Since this book was given a forward by Mark Gould, let's leave the importance and description of this book to him:
“Scales and arpeggios are the essential musical building blocks for mastery of EVERY instrument. These scale exercises from the classic Saint-Jacome Method, when practiced with focus and careful attention, will surely improve your trumpet playing. In order to optimize the value of this book, I would recommend practicing ALL the suggested variations in articulation.” Mark Gould, Juilliard School of Music. Principal Trumpet Emeritus, Metropolitan Opera
