Nordenstreng, K. A comparison between the semantic differential and similarity analysis in the measurement of musical experience.Scand. J. Psychol., 1968, 9,89–96.—Ten pieces of music were rated by a group of broadcasting sound‐controllers using two different scaling techniques, the semantic differential ratings of each sound on 32 scales, and similarity ratings for all pairs of sounds. The two scaling techniques were compared matching factor spaces by transformation analysis. The results indicate almost perfect similarity of the factor structures, which suggests that similarity analysis and the semantic differential in fact measure the same
