# MFCCs and chord recognition

This is my first time working with Mel-frequency cepstral coefficients and I have two questions....

1. Are some of the 13 coefficients strictly related to some sound properties like frequencies, amplitude, pitch or something ? For example if I'm interested only in sound pitch, are there some coefficients that carry that information and I can exclude the rest of the coefficients that carry other information to reduce the size of the vector ? Or those coefficients means nothing individually and they must be used all together as a whole ?

2. I'm trying to learn Chord recognition methods. I was thinking for calculating MFCC from a short Wave file where chord is played. (It is just a chord played on piano, there is no ambient noise or other instruments). And after I get the 13 MFCCs, cluster them to a centroid which describes the appropriate chord. (24 centroids, 12 for minor chords, 12 for major). I'm just wondering, are the MFCCs good descriptor for the present pitches in the sound ?
