Excellent as always!! I like the fact that you use the 6th and 7th natural positions of the trombone rather than the convenience of the F-attachment and play it on 1st and 2nd position! ! Thanks for sharing!! 👍 👍
If you want something similar, Daily Routines for the Student Trombone Player by David Vining has got a lot of lip slurs like this! Or if you're just looking for some good challenging lip slurs I definitely recommend the Brad Edwards Lip Slur Melodies book
