Music transcription of Javanese Gamelan using Short Time Fourier Transform (STFT)

Notation guide of traditional music such as Gamelan is very necessary for playing this instrument. There is a serious lack of artists who can add notation to represent gamelan, that cause arrangement research happens, the act of arranging and adapting a piece of gamelan notation. In this case, music transcription is the conversion process of music signal into numbers or symbols representation. The existence of this transcription research, the music can be played back using the results of transcription which used as a music notation guide in the play Gamelan. Process of transcription in this research use STFT (Short Time Fourier Transform) method. The results obtained in this paper were envelope signal from separation process the music signals into some channels of music notation in accordance with the fundamental frequency range of each music notation.
