These are recordings of the trumpet etudes for the Plano middle school All-Region audition coming up next month.
If you are just starting practicing don't start from the beginning. Learn the last measures of each first and work backwards from there. Remember that it never makes sense to "practice" groups of measures if you cannot play the measures in the group. Learn simple measures first and your practice sessions will flow.
I hope you find the recordings helpful. If you hit any snags please feel free to let me know in the comments.
