Abstract
In this study, a program was developed that allows one to listen to sounds existing in computer, with the algorithms based on signal processing logic which is available via Fourier Transform in MATLAB program. The heard sound is recorded when it is repeated by human voice, and its frequency is compared to the frequencies of existing sounds in the computer to obtain measurement results. The first version of the program to be developed used piano notes in the range of B3-D5. The program generates measurement results in graphic form, corresponding to notes sung. In addition, the frequency results are shown in the information display. One of the main objectives of the study is to develop a measurement system that could be applied in music special aptitude tests. In music aptitude tests, in the questions about sounds repeating, the jury’s perception is altered by factors such as fatigue, and candidates’ measurement results are affected by this problem. This program seeks to eliminate this negative effect in the measurements results of the aptitude test. The first version of the program developed in this study was tested on 10 people. The Pearson correlation analysis was performed with the aim of examining the relationship between achievement levels of students in one voice field and fixed frequency values. The result of this analysis was a meaningful, positive and high-level relationship between fixed values of 16 notes frequencies in the range of B3-D5 and singing values of the students regarding these 16 notes. Key words: Music education, music aptitude test, MATLAB, Fourier transform, aptitude test program.
Highlights
Music is an art which has an important place in society.Performance of music is observed in different dimensions in human life
The main objective of this study is concerned with this situation
In MATLAB software, codes were written based on algorithms that will be used to analyse the items below
Summary
Performance of music is observed in different dimensions in human life. Those who wish to pursue the art of music must possess a certain degree of musical ability. Whether at a professional or amateur level, people begin their musical training only once their level of aptitude has been determined. To this end, students' skills and aptitudes in terms of music are measured and assessed in musical aptitude tests.
