There have been threads in the recent past about keeping in shape/practicing while traveling, so I thought I'd share my recent/current experience.
I'm 7 days into a business trip in India that's scheduled for 3 weeks. Knowing that I'd be gone that long I decided that mouthpiece buzzing anole wasn't going to cut it, so I packed my pocket trumpet and Silent Brass system in my carry-on.
I'd never had problems with domestic travel but I was a bit nervous about international airports and their scrutiny. Fortunately, none of the security checpoints even mentioned the instrument.
When I finally got to the hotel I was hopeful that there would be a ballroom or something similar where I could go to play, but I'm in what's considered a "residence" hotel, so there are just guest rooms and no meeting areas.
So for now I'm relegated to playing only with the mute in. This isn't ideal obviously, but not a huge inconvenience. Out of a normal 1 1/2 to 2 hour daily practice routine I typically have a mute in for about 45 minutes, so I'm kind of used to it.
Since I won't be venturing very far from the hotel or office I'll have lots of time on the weekend to play, and I've managed at least 30 minutes a day so far, so I'm VERY happy I brought the horn with me.
