237 participants listened to a 37 second extract of original music for solo piano, and were asked to retrospectively verbally estimate elapsed duration. Differences were found for age (mean estimate for ages 5-8: 76.11 seconds, ages 9-10: 66.38, 11-13: 54.88 seconds, ages 14 to adult: 65.17 seconds) and a correlation found between adult age and estimate. Estimates were found to be significantly...

The proposed method is based on multiple-F0 estimation and makes use of the a priori knowledge that the observed spectrum is generated by a single monodic instrument. The predominan...
