I practice about 30-45 minutes total. 5-10 min warm up -5 min long tones (second-line G down to F# below staff; second-line G to third space C) -5 min Bach Chorale (I play 3-5 hymns which are about 3 bars each) 20 min of band music (jazz/symphonic) -run through each piece/ work on specific passages (I know all the notes and rhythms but I can't play them all [Bb above staff- High D]) 10 min cool down -Hold second-line G as long as I can (5 min) -Play G, F#, F, F#, G; whole notes @ 50 bpm (5 min) What must I do to extend range to at least High D, and increase endurance? I will play the following songs in an upcoming concert: Harlem Nocturne (arr. Mike Tomaro); Cool School Dropout (Les Hooper); 500 Miles High (arr. Victor Lopez) each is 1st trumpet. I doubt that I will be able to hit all the notes because I also play first for 2 of 5 songs in symphonic band's concert ( that same night and before jazz band). What must I do to improve range and endurance for after the concert? I've been practicing consistently but have not seen improvement yet. I try to play at mf or less when I practice. How free-blowing should it feel when I play or practice? I don't use much pressure or jam the mouthpiece in my face when tired, yet I feel a discomfort in my throat, like a "gentle burning." How do I improve that? Finally, concerning air, how do I move it faster? This isn't a concern until after thirty minutes or so of playing, when my lips are tired.
