Via the scale prepared before the experiment, the pretest was applied to both groups and during this period students were made to play Op.36 and No:2 by M. Clementi and groups?s technical and musical talent level were determined. During the research, according to an expert?s remark, in the 4-week period beginning from the 2nd week students played C.Czerny?s three equivalent etudes (No: 30, 36 ve 68) and the second group played J.B.
