The national pentatonic harmony has been extensively used and is being shaped as a relatively complete system. However,in many conservatories of music the traditional European harmony has long been taught while the national pentatonic harmony has been neglected. Consequently,the students know little about national homophonic forms. In their composition,the students often use traditional European harmony accompanied by five-tone canto,which results in the disjointedness of harmony and canto. Something should be done to change this irrationality.
