The Usage of Rubric in Evaluation of Different Properties of Cellos

The purpose of this research is to develop a method to test different properties of a given violoncello. The properties tested are the variety of color, vibrato production, capacity of volume, equality of sound among different registers, characteristic tone. The study is designed as descriptive research. The study group of the study consists of; three different handmade cellos, six expert lecturers on the field and a volunteer undergraduate student from cello arts of the music department of the conservatory of a state university in Central Anatolia, Turkey. Data have been obtained by a string instrument rubric (Y？R). The findings were tabulated and evaluations were made. According to the findings obtained, the importance of the objective approach in evaluating the sound properties of the instruments has emerged. The rubric was able to reveal the instruments with similar sound characteristics and distinguish the strengths of them. The graded scoring key rubric was found to be successful for turning the subjective evaluations into measurable objective results and solution proposals have been made for the usage of rubric for this specific purpose
