Aransemen Nada Alto, Tenor, dan Bass Menggunakan Algoritma Genetika

Hendry Setiawan, Windra Swastika, Ossie Leona, Oesman Hendra Kelana


harmony is the key element in producing a piece of music. When a song will be sung by the choir, the song should be arranged in a division of sopran, alto, tenor and bass voice parts first. Unfortunately, not everyone has the ability to determine the harmonic notes division. There are therories to make a harmonic division of voice parts, so that an application for the notes arrangement can be made. A music application can be developed by using Application Programming Interface(API) JFugue that can be represent the music into the programming language. This application is made by implementing the Genetic Algorithm. Chromosome in Genetic Algorithm contains the music notes that have translated into the value of algorithmic music and its duration. Selection is done by giving reward for the correct notes arrangement and punishment for the wrong notes arrangement. The testing result of this application is already showing a good result. The results of fitness function are in accordance with the verifivation result from the expert. The average percentage of truth not arrangement is above 98%.

Keywords— Genetic Algorithm, Harmonization, Music.
