Hi Greg, thanks for your reply. I needed your statement that lip slurs are the trickiest thing in trumpet playing because I am already 59 and thats why I am a little bit impatient. I will take your advice and take my time, doing it slower and just wait for the day it will go easier. As I wrote, sometimes I can do it and than the other time it wont work as before. Okay I will let you know how I progress.
In the first week of March I am in Florida and have some golf sessions, I will think of you and your golf experience. I will do the mental training there, because I cant play trumpet there, the neighbours would kill me, I think they would even kill Arthuro Sandoval.

See you
