Hi all I had a question regarding practicing without an instrument. I have a job that requires a lot of travel with extended stays away from home. Unfortunately, this makes bringing my euphonium along rather inconvenient. Naturally, when I come back home to practice with my instrument my playing has deteriorated a little bit. I wanted to ask if anyone had any advice on practicing without a euphonium.

I have started taking my mouthpiece and buzzing long-tones but that is about all. Would it be practical to do Arban tonging exercising with buzzing to keep my embouchure among other things or is that not practical? Any other advice on practicing without an instrument would be appreciated as well.

As an aside I have picked up the mandolin as it is a lot more travel friendly and still lets me to get my music fix but I really enjoy euphonium as it is the first instrument I've learned and I don't want all the practice time I've put in to go to waste.

Thank you for any advice.
