I am begining to practice a concerto that requires solo tuning. Since I am not primarily a solo player, and merely want to learn a concerto for the betterment of my playing and college auditions, I do not want to buy solo tuning strings. The string coach at my school said that it would be ok to tune up my regular strings to solo tuning to practice as long as when I was done I tuned them back down (I play Obligatos). I am very affraid of the extra tension this will add to the strings and affraid of breaking a string. Is this dangerous?? PS. I want to practice it in solo tuning because the conductor at my high school might let me play a movement of the concerto with my high school orchestra. I don't want to learn it sounding one way and then go to practice with them and have it be a whole step higher because that would mess with my ears too much.
