[pouya_jahanaray]

Hello , I have a question . I have a serious problem in measure (bar) 35,36,37 . Right hand's Quaver and left hand's Tuplet . I play it well in slow speed but in highest speed I can't play it . I practice it in slow speed for 4,5 month but I can not improve it to high speed . I have an other problem like this in measure 171,172,... (Ossia) . This parts are very difficult !
Please help me to solve this problem . thank you .
