Beat tracking – i.e. deriving from a music audio signal a sequence of beat instants that might correspond to when a human listener would tap his foot – involves satisfying two constraints: On the one hand, the selected instants should generally correspond to moments in the audio where a beat is indicated, for instance by the onset of a note played by one of the instruments. On the other hand, t...

The number of scholars following the tempo approach in fertility continues to grow, whereas tempo-adjustment in mortality generally still is rejected. This rejection is irrational in principle, as the basic idea behind the tempo approach is independent of the kind of demographic event. Providing the first empirical application to a substantial problem, this paper shows that mortality tempo-adju...

We investigated whether and how the timing of musical rhythms changes with tempo. Twelve skilled pianists played a monophonic 8-bar melody in 21 different rhythmic versions at 4 different tempi. Within bars, the rhythms represented two isochronous patterns and all possible ordered pairs and triplets of different note values with ratios from the set {3, 2, 1}. The 3-note rhythms also occurred in...

One of the difficulties with assessing tempo or beat tracking systems is that there is no standard corpus of data on which they can be tested. This situation is partly because the choice of data set often depends on the goals of the system, which might be, for example, automatic transcription, computer accompaniment of a human performer, or the analysis of expressive timing in musical performan...

Automated beat tracking and tempo estimation from music recordings become challenging tasks in the case of nonpercussive music with soft note onsets and time-varying tempo. In this paper, we introduce a novel mid-level representation which captures predominant local pulse information. To this end, we first derive a tempogram by performing a local spectral analysis on a previously extracted, pos...

From March 15th to August 31st 200, I attended a research internship within the Comuter Science and Artificial Intelligence Laboratory at the Massachusetts Institute of Technology under the supervision of Nancy Lynch. Within her group, the Theory of Distributed Systems Group, I worked on the Tempo Toolset develloped by Veromod Inc. and on six examples for the Tempo Toolset User Guide and Refere...

O objetivo do presente estudo foi determinar os parâmetros farmacocinéticos da ropivacaína encapsulada em lipossomas após anestesia local em 14 voluntários sadios. Neste estudo randomizado, cruzado e duplo-cego, os voluntários receberam anestesia infiltrativa na maxila de ropivacaína a 0,5% encapsulada em lipossomas e ropivacaína 0,5% com epinefrina a 1:200.000 em duas sessões distintas. Amostr...

This paper presents an interface for finding interpretations of a user-specified music, Query-by-Conducting. In classical music, there are many interpretations to a particular piece, and finding “the” interpretation that matches the listener’s taste allows a listener to further enjoy the piece. The critical issue in finding such an interpretation is the way or interface to allow the listener to...

BACKGROUND AND AIMS A long existing notion is that the presence of music might affect gambling behavior. In spite of this, little empirical research on the subject exists. The main aim of the present study was to corroborate and elaborate on the existing findings concerning gambling and music through a laboratory based experiment. METHODS A nonclinical sample of 101 undergraduate students (72...
