I am going on a vacation which will last roughly 7 long day! These days I cannot play my trumpet... What can I do to keep my endurance... and overall embouchure intact? I gave buzzing on my mouthpiece a thought but are there any particular exercises I should look into on the mouthpiece? I just hate not having the horn there for 7 days... Could this possibly beneficial if I buzzed daily? ( this is something I normally never do ) Thanks so much!
