CECILIA YIBIRIN'S THREE PIANO ETUDES HAD THEIR WORLD PREMIERE IN 2021. THEIR LEVEL IS INTERMEDIATE TO ADVANCED. THE PRACTICE OF THESE ETUDES HELPS PIANO STUDENTS TAKE A BIG STEP TOWARDS THE GREAT CONCERT ETUDES OF CHOPIN, LISZT, RACHMANINOFF, MOSZKOWSKI AND OTHERS. THE TECHNICAL CHALLENGES INCLUDE: FAST FIVE FINGER ACTION AND ARM ROTATION (ETUDE NO. 1), DOUBLE THIRDS (ETUDE NO. 2),  OCTAVES (ETUDE NO. 3). THEY ARE A GOOD ADDITION TO A YOUNG PIANIST'S REPERTOIRE.
