hello after a long time! well i played wieniawsky after all but my teacher promised me to let me play barber this year (in our conservatorie they don't like modern composers that much but i'll step my foot down!) You have been very very helpful, thanx a lot!
P.s. I started studying devil's trill and i found that paganini's caprice n.6 helps a lot for the trill part. What do you think about this sonata?
