26 New Etudes for Trumpet: In 13 major and 13 minor keys with scales & arpeggios [Repost]

A companion book to: "Concert Duets for Trumpet"
Words from the author:
It is important that aspiring musicians become fluent in all of the major and minor keys. When I was a student, I was never entirely satisfied with the few choices of resources that contained well-written etudes in all keys.
There have been some attempts but many of them have some standard keys missing, others are purely technical and lacking in musicality. Others were too high or too long and left them out of reach of emerging players. Further, finding a single resource that laid out all of the major and minor scales and arpeggios in a simpler manner was more difficult than it should have been.
I did not need or want several pages of the same scale written out in a dozen or more rhythmic patterns and meters. As a result, I started playing the scales from memory in a manner that suited me. I have included these scales in this book. I also wrote them in such a way to include arpeggios at the end of each scale. This eliminates the need to have separate scales and arpeggio exercises.
I recommend that all players from emerging ones to professionals play all the major and minor scales every day. Once the scales are memorized, the player will be ready to begin playing them with more speed. Eventually, all the scales can be played quite quickly and be completed in a very short time. At this point, you will find that many things may be easier for you as a player: sight-reading, transposition, or improvisation for example.
