Based on the previous studies of the guitar chord recognition systems, there is an indication that a study can still be carried out. In this case, an indication to study a lower number of coefficients of feature extraction in a guitar chord recognition system. The purpose of this study is to obtain a lower number of coefficients of feature extraction in a guitar chord recognition system than the previous studies. In this study, the guitar chord recognition system uses MFCC (Mel Frequency Cepstral Coefficients) based feature extraction with Kaiser windowing. This study evaluated three parameters from the system, namely the lowest mel filter frequency and the number of mel filters in the mel filter bank, and also the shape factor of the Kaiser window. The results showed that by using only four coefficients of feature extraction, it could achieve an accuracy of up to 92.14%. As a note this accuracy was carried out by using 140 test chords.
