I'm with Gary on this one. Try to play more lyrically, or play it as you would want to sing it. Think about the words as you are playing the notes. This helps me. If I don't know the words, I can't play the tune properly. Maurice Murphy, the principal trumpet for the LSO said this during a masterclass video I watched, and it has stuck with me since : LSO Masterclass - Trumpet - YouTube I understand this is easier said than done, but you'll get it with lots and lots and lots and lots of practice. Phrasing, phrasing, phrasing! That said, I am not a professional, I am an amateur trumpeter, but a seasoned musician. So take this advice for what it is worth to you. Kudos on posting a video, I've wanted to do this for a while but I haven't had anything that I thought was good enough yet. Good luck to you, find a teacher that inspires you and don't quit no matter how frustrating it is.
