The article “A Music Key Detection Method Based on Pitch Class Distribution Theory” (J. Sun, H. Li, and L. Ma, International Journal of Knowledge-based and Intelligent Engineering Systems, 2011:165–175) describes a method of analyzing digital music files to determine the key in which the music is written. In a sample of 307 pop music selections, the key was identified correctly in 245 of them. In a sample of 347 new-age selections, the key was identified correctly in 304 of them. Can you conclude that the method is more accurate for new-age songs than for pop songs?
