Hi, I haven't posted here for some time. Just a reminder about myself, I am a thirteen year old, been playing trumpet for three to four years now. I am going to audition for a selective orchestra in some time. I have a few questions about what to do, I really haven't done many auditions before. I am playing two movements from Hummel Trumpet Concerto, the fast first and slow second. In addition, I am required to play major and minor scales. I have prepared some: 1 octave: C, D, Eb, F, Bb, cm, dm, em, fm, bm, 2 octave: G, F#, gm, f#m, g-g chromatic. First, for the minor scales, which form should I play? So far, I have been practicing the natural and melodic minor. Then, any general tips or advice on the Hummel? Lastly, what suggestions are there regarding the overall audition? When, how long, should I warm up? If allowed to choose scales, which one should I play? The easiest, hardest, highest, etc.? Thanks for the help.
