The present paper reports the results of an elabo- rate study which explores (1) who potential users of MIR systems are, (2) how they perceive affects in music, and (3) what structural descriptions of music best characterize their understanding of music expression. 79

We show that a set of affective/emotive, structural and kinaesthetic descriptors can be used to formulate a query which allows the retrieval of intended music. A semantic music recommendation system was built, based on an elaborate study of potential users and an analysis of the semantic descriptors

We summarize results of an elaborate user-study that explores who the users of music information retrieval systems are and what structural descriptions of music best characterize their understanding of music expression. Our study reveals that perceived qualities of music are affected by the context of the user. Subject dependencies are found for age, music expertise, musicianship, taste and familiarity with the music. Furthermore, interesting relationships are discovered between expressive and structural features. These findings are validated by means of a Semantic Music Recommender System prototype. The demonstration system recommends music from a database containing the quality ratings provided by the participants in a music annotation experiment. A test in the real world reve...

Most previous studies made use of videos of actors or dancers portraying emotions through choreography. The current study applies emotion induction techniques and free movement in order to examine the recognition of emotional content from dance. Observers (N = 30) watched a set of silent videos showing depersonalized avatars of dancers moving to an emotionally neutral musical stimulus after emotions of either sadness or happiness had been induced. Each of the video clips consisted of two dance performances which were presented side-by-side and were played simultaneously; one of a dancer in the happy condition and one of the same individual in the sad condition. After every film clip, the observers were asked to make forced-choices concerning the emotional state of the dancer. Results revealed that observers were able to identify the emotional state of the dancers with a high degree of accuracy. Moreover, emotions were more often recognized for female dancers than for their male counterparts. In addition, the results of eye tracking measurements unveiled that observers primarily focus on movements of the chest when decoding emotional information from dance movement. The findings of our study show that not merely portrayed emotions, but also induced emotions can be successfully recognized from free dance movement.

In this paper, a new system for the automatic transcription of singing sequences into a sequence ... more In this paper, a new system for the automatic transcription of singing sequences into a sequence of pitch and duration pairs is presented. Although such a system may have a wider range of applications, it was mainly developed to become the acoustic module of a query- by-humming (QBH) system for retrieving pieces of music from a digitized musical library. The first part of the paper is devoted to the systematic evaluation of a variety of state-of-the art transcription systems. The main result of this evaluation is that there is clearly a need for more accurate systems. Especially the segmentation was experienced as being too error prone ( % segmentation errors). In the second part of the paper, a new auditory model based tran- scription system is proposed and evaluated. The results of that eval- uation are very promising. Segmentation errors vary between 0 and 7 %, dependent on the amount of lyrics that is used by the singer. The paper ends with the description of an experimental stu...

This music system provides a game-like environment in which a musician can create a digital painting by playing an acoustic musical instrument, by moving the body in different directions, and by selecting colours using a pressure mat. The experiment aimed at getting a better insight into the possible relationship between flow experience and presence. Based ...
Assessing a Clarinet Player's Performer Gestures in Relation to Locally Intended Musical Targets

Of particular interest is the match between the musician's mental focus on musical targets (the so-called musical intentions) and the expressive (or so-called auxiliary) body movements. To what extent are these related to each other? And what does this relationship reveal about mind–body connections? To approach these questions, a case study was set up around a clarinet solo performance ...
