We investigate the time series of the segments from a Korean traditional song``Gwansanyungma'' and a western song ``La Mamma Morta'' using chaotic analysistechniques.  It is found that the phase portrait in the reconstructed state space of thetime series of the segment from the Korean traditional song has a more complexstructure in comparison with the segment from the western songs. The segmentfrom the Korean traditional song has the correlation dimension 4.4 and twopositive Lyapunov exponents which show that the dynamic related to the Koreantraditional song is a high dimensional hyperchaotic process. On the other hand,the segment from the western song with only one positive Lyapunov exponent andthe correlation dimension 2.5 exhibits low dimensional chaotic behavior.Comment: 23 pages including 10 eps figures, latex, to appear in J.
