In December, I will be going overseas for a month and 5 days. I'll be travelling around the UK and France and staying in hostels, and am wondering if it's worth me finding an alternative to bringing a trumpet with me? I feel that not playing at all for a month is going to be detrimental, but I am doubtful of being able to find enough time during my trip to practise. Would it be worth getting myself one of those P.E.T.E. devices to keep my embouchure active as far as muscles are concerned? Would a month with just the P.E.T.E. be too long? I don't have a problem taking a trumpet, as I have an "expendable" one that isn't my main horn, but the issue might arise in finding the time! Any ideas would be greatly appreciated!
