abstract: The purposes of this research were to observe the power spectrum and the evolution pattern of the power spectrum of large gong (gong ageng) Kagungan Dalem Gongso Kanjeng Kyai Guntur Sari. Power spectrum was important because physical quantities involved an energy transfer which had a close relationship with acoustic energy detection in the hearing process. The data in this research were secondary. The source of sound signal was a set of large gong (gong ageng) which consist of gong ageng 1 and gong ageng 2, while the sensor to detect the sound signal was condenser microphone. As soon as the instruments were played, the condenser microphone was put in the resonance box (behind of gong) in order to record the signal from the first time they played until the amplitude was decayed. The result of the power spectrum analysis using Parseval’s theorem which was implemented in own made program by Matlab (R2010a) showed that, in the large gong (gong ageng) instrument, the biggest sound power was owned by the second harmonic component which is 88,2 Hz. The analysis result of the power evolution of large gong (gong ageng) showed that all frequency components had regular evolution pattern as well as regular interval which resulted in wave (ombak) phenomenon.
