How can I get sheet music to self-assess my trombone grade level?
I'm getting back into trombone after not playing since high school, and just curious about approximately what grade level I'm at. I'm in one very amateur community concert band where the highest level stuff is Grade 3, and one more intermediate level community big band where we're playing at a bit of a higher level. I'm thinking I'm probably really at Grade 4-5ish, but it'd be nice to have some pieces to get a better feel for where I'm at.
Looking at something like this: https://www.abrsm.org/sites/default/files/2023-10/Brass%202023%20Practical%20syllabus%20%284%20Trombone%29%2020230907.pdf or this: https://lcme.uwl.ac.uk/media/cj5pxhqh/trombone-rep-list-from-2011.pdf there's a clear syllabus of pieces at each level, but it's not trivial to find the sheet music. Is there any public source for examination sheet music?
There's also things like this but it doesn't quite have enough detail for me to fully get an impression of where I'm at.
I know a proper examination is the way to go, but are there any good examples of sheet music for different grade levels to have a blast through, to see at which levels I start to have difficulties?
