Melody Extraction using Frequency Analysis

Abstract

Music is an important art form that surrounds us in our daily lives. To pursue a career in music and utilize musical knowledge, one must rely on expertise and training to develop skills. Consistent practice can help improve one's skills greatly. Nowadays, the use of technology plays a role in enhancing musical skills, resulting in rapid progress in human musical development.  Technology can efficiently connect human needs and facilitate the process of knowledge development, which can reduce production time and lead to more efficient music output.

In this research, the focus was on studying the pattern of the frequency analysis of sound, which is an important part of finding musical notes from the sound produced. The method helps to reduce the time required to write down musical notes for musicians or composers. The researchers studied the process of sound production, which generates a standard frequency value according to the level of high and low sounds, resulting in the creation of music. After the musicians or composers produce their musical works, they record the sound to use it for future benefits. If they need to use musical notes, they can do so immediately through the frequency analysis process. This research was able to record sound without noise to obtain the desired sound quality. Then, we used the principle of frequency analysis to determine the sound level by comparing the frequency with the musical notes. This method can be applied in music production to help reduce the time required to write down musical notes one by one. However, this process still requires basic knowledge of music to help analyze or observe errors in musical notes or rhythms, as these are important aspects of creating musical works.
