This preliminary study investigates the relationship between tempo indications in a score and the tempo performed by musicians. As several 18 century theorists point out, the chosen tempo should depend not only on the tempo indication, but also on other factors such as the time signature and the fastest note values to be played. It is examined whether the four main tempo indications (Adagio, An...

In the current state-of-art beat tracker, it is common that a specific algorithm do the best on particular kind of audio. For example, the algorithm based on two-fold dynamic programing have sequential 1 st place on time-varying-tempo MAZ dataset of MIREX audio beat tracking. This study proposed a tempogram-sensing-vector (TSV) method to be adaptive to time-varying-tempo and stable-tempo excerp...

Automatic beat tracking and tempo estimation are challenging tasks, especially for audio music with timevarying tempo. This paper proposes a two-fold dynamic programming (DP) approach to deal with beat tracking with time-varying tempo. In particular, the first DP computes the tempo curve from the tempogram. The second DP identifies the optimum beat positions from the novelty and tempo curves. E...

Many studies have revealed the influences of music on the autonomic nervous system (ANS). Since previous studies focused on the effects of acoustic tempo on the ANS, and humans have their own physiological oscillations such as the heart rate (HR), the effects of acoustic tempo might depend on the HR. Here we show the relationship between HR elevation induced by acoustic tempo and individual bas...

In the expressive performance of music variation of tempo plays a major role in shaping and structuring the piece. We distinguish two aspects of tempo, the current tempo and the timing of individual notes with respect to the current tempo. Those two notions are influenced differently by the characteristics of the performed score. The relation between score and timing/tempo has many facets, one ...

Speakers vary their speech tempo (speaking rate), and such variations in tempo are quite noticeable. But what is the just noticeable difference for tempo in speech? The present study aims at providing a realistic and robust estimate, by using multiple speech tokens from multiple speakers. The JND is assessed in two (2IAX and 2IFC) comparison experiments, yielding an estimated JND for speech tem...

Behavioral studies suggest that preference for a beat rate (tempo) in auditory sequences is tightly linked to the motor system. However, from a neuroscientific perspective the contribution of motor-related brain regions to tempo preference in the auditory domain remains unclear. A recent fMRI study (Kornysheva et al. [2010]: Hum Brain Mapp 31:48-64) revealed that the activity increase in the le...

In this study, the host-guest behavior of poly(amidoamine) (PAMAM) dendrimers bearing amine, hydroxyl, or carboxylate surface functionalities were investigated by paramagnetic NMR studies. 2,2,6,6-Tetramethylpiperidinyloxy (TEMPO) derivatives were used as paramagnetic guest molecules. The results showed that TEMPO-COOH significantly broaden the ¹H NMR peaks of amine- and hydroxyl-terminated PAM...

The data reported in this paper are complementary to the characterization of 4-(phenylazo)-benzoyl-2,2,6,6-tetramethylpiperidine-1-oxyl radical (AzO-TEMPO) and of the 4-(2-thienylazo)-benzoyl-2,2,6,6-tetramethylpiperidine-1-oxyl radical (ThiO-TEMPO) before and after their grafting to two polyethylene matrices (a copolymer ethylene/α-olefin (co-EO) and a high density polyethylene (HDPE)). Partic...
