This study aims to develop a scale to measure the attitudes of Music Education Department (Music Education Department: MED) students towards the choir lesson. With the developed scale, it was aimed to determine the attitudes of MED students towards the choir lesson. The developed scale is a 5-point Likert-type attitude scale. After the scale development phase, factor analysis was performed on the scale and a fit model study was conducted regarding the scale items and dimensions. The scale was created as a 40-item draft scale and was administered to 348 MEABD students. Within the scope of the validity and reliability studies of the attitude scale towards the choir lesson, the Cronbach Alpha reliability coefficient for general reliability was calculated as 0.924 before the analysis and 0.920 after the analysis. Analyzes evaluated at 95% confidence intervals. (p <0.05)As a result of exploratory and confirmatory factor analysis within the scope of construct validity, the draft scale was reduced to a 27-item scale. Whether the data structure was suitable for factor analysis was checked using the KMO (Kaiser-Meyer-Olkin) test and Bartlett test methods. The KMO test value was 0.919 and the Bartlett test was 8147,552 (p<0.05). The obtained 27 - items attitude scale for the chorus lesson consists of 4 factors. These dimensions are “Behavioral”, “effective”, “anxious” and “perceptual” dimensions. The total variance explained by the attitude scale for the chorus lesson, which consists of four dimensions, was determined as 57.582%. The load values of the scale items ranged from 0.45 to 0.79. In addition, after the factor analysis, item analysis was carried out regarding the whole scale and each sub-dimension. The relationships between the whole scale and its subscales and between the subscales were examined and the significance levels of relationships were examined.  (p <0.05)The scale, which was reduced to 27 items with factor analysis, and the compatibility of the models established with confirmatory factor analysis, were examined. Within the scope of confirmatory factor analysis, χ2/df (chi-square/degrees of freedom) value was found to be 1.30, which shows that the model has a perfect fit. It is seen that the model has RMSEA value of 0.084, GFI value of 0.81, AGFI value of 0.77, RMR fit index of 0.070 and SRMR fit index of 0.051, NFI value of 0.94, NNFI value of 0.95, and CFI value of 0.97. As a result of the research, a valid and reliable attitude scale developed for the Choir lesson.
