Practicing piano and memorizing piano pieces effectively have been a challenge for classical piano students in the conservatory. Specific method is needed to be applied during practice sessions to improve the productivity in practicing. My aim in this research is to evaluate the outcome after applying Systematic Practice Method in practicing. With this purpose, a group of participants who applied Systematic Practice Method was compared with a group of participants who did not apply any method. These participants were given a similar piano piece to memorize in three days, with an hour of practice each day. A significant improvement in the speed of memorizing and effectiveness in practicing was revealed throughout three days of the experiment. Furthermore, after conducting the experiment, I distributed questionnaires to participants who applied Systematic Practice Method during practicing, and received positive remarks and feedbacks concerning the method.
