This book has puzzled me for quite some time. We all know Johanson’s “Daily Exercises” (LINK) but these Instructive Studies focused on rhythm and articulation have been out of print for decades.
The mystery lies in the etude numbers. This book begins on exercises 33 and ends on exercise 50. Listings for this book in all public records show it as a 21 page book and do not suggest that it is an extract from a larger work or part of a multi-volume series. It was published in this arrangement by Cundy-Bettoney many moons ago, and stands on its own as a wonderful study book of late intermediate to early advanced trumpet studies. I love their technical challenges almost as much as I champion their idomatic writing.
I have included some samples pages for you to try, with a full PDF download available above.
*NOTE: Do you have any background on the exercise numbering? If so, be in touch!
