Polyphonic signal analysing process becomes the basic topic of signal analysis currently. Furthermore, analysis on the signal of music is also becomes the part of this topic. The main chosen instrument is sasando. As the matter of fact, this is not only about its characteristic sound but also because of the need for the preservation of this musical instrument which is about getting to be abandoned. This research will apply cross correlation method. Cross correlation method will done through signal comparing. We compare polyphonic signal (chord), which having multiple fundamental frequencies. The compatibility can be obtained from amplitude score as the result of Cross-correlation process.
