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?
