Automatic Comparison of Human Music, Speech, and Bird Song Suggests Uniqueness of Human Scales

The uniqueness of human music relative to speech and animal song has been extensively debated, but rarely directly measured. We applied an automated scale analysis algorithm to a sample of 86 recordings of human music, human speech, and bird songs from around the world. We found that human music throughout the world uniquely emphasized scales with small-integer frequency ratios, particularly a perfect 5th (3:2 ratio), while human speech and bird song showed no clear evidence of consistent scale-like tunings. We speculate that the uniquely human tendency toward scales with small-integer ratios may relate to the evolution of synchronized group performance among humans.

Automatic Comparison of Global Children’s and Adult Songs Supports a Sensorimotor Hypothesis for the Origin of Musical Scales

Music throughout the world varies greatly, yet some musical features like scale structure display striking crosscultural similarities. Are there musical laws or biological constraints that underlie this diversity? The “vocal mistuning” hypothesis proposes that cross-cultural regularities in musical scales arise from imprecision in vocal tuning, while the integer-ratio hypothesis proposes that they arise from perceptual principles based on psychoacoustic consonance. In order to test these hypotheses, we conducted automatic comparative analysis of 100 children’s and adult songs from throughout the world. We found that children’s songs tend to have narrower melodic range, fewer scale degrees, and less precise intonation than adult songs, consistent with motor limitations due to their earlier developmental stage. On the other hand, adult and children’s songs share some common tuning intervals at small-integer ratios, particularly the perfect 5th (~3:2 ratio). These results suggest that some widespread aspects of musical scales may be caused by motor constraints, but also suggest that perceptual preferences for simple integer ratios might contribute to cross-cultural regularities in scale structure. We propose a “sensorimotor hypothesis” to unify these competing theories.

The Thermal Feedback Influencer: Wearable Thermal Display for Enhancing the Experience of Music Listening

Ishikawa Y., Kawazoe A., Chernyshov G., Fujii S., Nakatani M.

Lecture Notes in Electrical Engineering （Lecture Notes in Electrical Engineering） 535 162 - 168 2019年

This paper describes a new wearable thermal display, the Thermal Feedback Influencer, that can provide chilling stimuli to the skin in order to enhance emotional experiences of music listening. We developed a prototype device that can be attached to behind the ear. The device is designed to be small and lightweight enough to be worn comfortably. In this work, we describe basic concepts of this research, preliminary test results, details and evaluation of the developed prototype. We also summarize methods to provide thermal feedback with music and discuss the possible applications and future research plans.
