Ok I played trumpet for four years (grade 7-11) then quit. a month ago I decided i wanted to play again and rented a trumpet and started practicing. I joined a community band and yesterday we had rehersal, it was the first time I played with them. I was playing a 3rd trumpet part, no notes above a G, but by the end my lips we really tired. (im not sure if this has anything to do with the reason for this post) today after my sleep my lips felt better again but different, I assumed they were still recoving a little from playing yesterday. they kinda felt smooth or something. just now I started to mess around on my trumpet trying to play some high notes. I was thinking about how someone said think about whistling. so i tired whistling as high as I could and kinda held my mouth and tongue in place and applied the trumpet. I could squeak some really high notes out but it sounded like crap. Then after some experimenting i discovered that if i changed my embouchure to 2/3 top lip 1/3 bottom lip(previous embouchure 3/5 bottom lip 2/5 top) I could produce a much nicer sound and had waaaaay more control. I used to have a lot of trouble slurring from down to up but now with this change I can go from pedal C to double C and back down easily. before this my highest note i could play was a high C but not with a lot of volume and I had to apply a good amount of pressure. now i don't need much pressure at all. the problem now is I am not very accurate and im not really sure how my tone has changed in the middle register because i was playing with a practice mute. i did take it out and played quietly just to make sure it the mute wasn't the reason for this. Should I keep playing with this new embouchure and work on my tone and accuracy? am I doing something that I will regret? this feels like such a wild discovery and im very excited, but also afraid I will forget what i was doing tomorrow. or perhaps this is just some fluke?
