One reason we seem to put a limit to our high notes is because the studies we practice do not include material in that register. Even the Arban Method is very dated in this area.
So the question should be “where can I find decent material which includes higher notes than trumpet books offer”?Here is one such book and it will open a whole new world of material to advance your higher range playing.
“Gekeler Method for Oboe”
by Kenneth Gekeler
The material in this method is perfect for the trumpet player who has developed a solid range up to and including a high C. When first perusing these exercises, one realizes that all of the notes seem to be transposed a third higher than one would expect in a trumpet method. Raising your practice material a third is exactly what you need. Any higher will create more effort than would be needed at this point.
You will also find that each etude is short, which is also a great benefit to the player for you will not be pounding away at your lip for extended periods of time. The flowing melodies in this collection will also be a pleasure to perform and in addition to improving your higher playing you will be performing in a melodic fashion rather than repeating dull and boring scales.
I have included the first page of this fine book so that you can get started to gain confidence in your upper register. Also included is an MP3 demonstrating how you can benefit from my “Rest As Much As You Play” routine. If this form of practicing is new to you, “by all means check out my site” trumpetlessonsonline.com where it is more fully explained.
Note that the etudes have been recorded separately on both the left and right channels. On day one, listen to the left channel and continue playing the second line, etc.
On day 2, begin after the four bar click track and rest on the even numbered lines.
By doing this, you will increase you endurance as well as help expand your sight reading ability.
