This is a summary of an article from the April 1981 edition of The Instrumentalist. I encourage you to find the original article and read it in full. As in every summary, there is much more than can be included in this post.
In this article Harry Jenkins describes when he was able to study with Max Schlossberg while in school. Jenkins says, "he used 2 main sources of material--daily drills he wrote out for each student by hand and Arban. His success was due to the following outline he used in teaching" (unless otherwise indicated page references in this outline refer to Daily Drills and Technical Studies by Max Schlossberg).
1. The Warm Up - Daily Drills
2. Scale or Chord Studies (10-15 minutes)
3. Short Chosen Studies (he would chose specific studies for each student according to their need at the time)
Arban - pages 28 - 36
|28||18, 19, 20|
|42||16, 17, 18|
Arban - Characteristic Studies
pages 285-299 (Nos. 2, 3, 6, 7, 8, 9, 10, 11, 12, 13)
"These exercises were particular favorites of Max Schlossberg."
4. Song Material
"The most inspiring part of the lesson stressed phrasing and tone quality. Schlossberg would pick an operatic aria from the song section (Arban) and give us a little background of the singer’s role. First, an advanced student was chosen to play as model for the rest of us."
5. Theme and Variations
"Sometimes Max Schlossberg would choose a song with theme and variations. "Keel Row" was a favorite of his (including double tongueing and triple tongueing). Sometimes he would pick from the back of Arban.
"He would split the group in half for the 2 parts of a duet. This provided variety and added interest and improved ability to hear and play harmony."
"From time to time Max Schlossberg would include orchestral excerpts-trumpet calls from Carmen, Fidelio (Leonore Overture #3), or Reinzi (overture) were some that were used. A penny was awarded to someone who played them especially well."
8. Characteristic Studies
"This was usually the grand finale of the lesson and much time was spent on the study chosen for the week. It was used to review most of the playing skills and musicianship."
9. Special Ensemble Music
"At times he would bring in the Hoch Trumpet Quartets or speciallly written manuscript written material for the group."
I hope you have found this information interesting. Here is the link to Max Schlossberg’s Daily Drills and Technical Studies. These exercises were hand written for the students by Schlossberg himself when Mr. Jenkins studied with him--they were later collected and made available to everyone in this volume. This is standard material for any serious trumpet student.
