The main purpose of this study is to develop a scale to determine students' attitude levels on individual instruments and individual instrument courses in instrument training, which is an important dimension of music education, and to conduct a validity-reliability research of the scale that has been developed. The scale consists of 16 items. The validity-reliability research of the scale has been done on "128" students in the Department of Music Education of N.E.U., A.K.E.F, F.A.E.D. The data obtained were evaluated by the package software Spss 16.00. The structure validity of the scale was examined by factor analysis, and through the findings obtained it has been determined that the scale has two factors. According to the results of the rotated components matrix, Kaiser-Meyer-Olklin value is 0.95 and Barlett test result was found significant (p< 0.05); chi-square values of 2383.17, df = 136 are relevant for exploratory factor analysis. It is found out that Cronbach's Alpha reliability coefficient containing all items of the scale is 96, Cronbach Alpha reliability coefficient for evaluating the attitude level on individual instrument is 0.95, and Cronbach Alpha reliability coefficient for evaluating the attitude level on individual instrument course is 0.95. As a result, it is detected that the scale could be used trustfully in determining students' attitude levels on individual instruments and individual instrument course.
