We examined the relative stability of pitch, tempo, and rhythm in maternal speech and singing to prelinguistic infants. Mothers were recorded speaking and singing to their infants on two occasions separated by 1 week or more. The pitch level and tempo of identical utterances were highly variable across the 1-week period, but these features were virtually unchanged in song repetitions. Rhythmic ...

We find a quantum mechanical formulation of proper time for spin 1/2 particles within the framework of the Dirac theory. It is shown that the rate of proper time can be represented by an operator called the “tempo operator”, and that the proper time itself be given by the integral of the expectation value of the operator. The tempo operator has some terms involving the Pauli spin matrices, and ...

O presente artigo apresenta um estudo contrastivo entre as propostas de análise do tempo na primeira e segunda edições do HAREM. Discutimos, entre outros aspectos, as principais vantagens e inconvenientes de uma e outra, tendo em linha de conta os prinćıpios teórico-metodológicos subjacentes ao modelo geral do HAREM. A discussão é feita com base nas expressões temporais compreendidas nas colecç...

In this paper we present preliminary work examining the relationship between the formation of expectations and the realization of musical performances, paying particular attention to expressive tempo and dynamics. To compute features that reflect what a listener is expecting to hear, we employ a computational model of auditory expectation called the Information Dynamics of Music model (IDyOM). ...

The research described in this paper focuses on global tempo transformations of monophonic audio recordings of saxophone jazz performances. More concretely, we have investigated the problem of how a performance played at a particular tempo can be automatically rendered at another tempo while preserving its expressivity. To do so we have developed a case-based reasoning system called TempoExpres...

This paper presents an application of Empirical Mode Decomposition (EMD) on the induction of notated tempo from music recordings. At a first stage, EMD is employed as a means to segment music recordings into segments that exhibit similar rhythmic characteristics. At a second stage, EMD is used in order to analyze the diagonals of the Self-Similarity Matrix of each segment, so as to estimate the...

In an expressive performance, a skilled musician shapes the music by continuously modulating aspects like tempo and loudness to communicate high level information such as musical structure and emotion. Although automatic modelling of this phenomenon remains beyond the current state of the art, we present a system that is able to measure tempo and dynamics of a musical performance and to track t...

Tempo perception has been studied using many different methodologies in trying to isolate the motion patterns of a conductor in experimental stimuli. In doing so, the context of conducting has been ignored including secondary bodily motion, expression and communication from the conductor, and conducting gestures outside of the realm of tempo control. The aim of this study is to test the ability...

This is an acoustic study of prosodic effects on segmental durations with reference to syllable structure, stress, focus and tempo in Greek. Disyllabic nonsense words with one, or two, or three consonants in the initial syllable were examined in stressed/unstressed, focused/unfocused and normal/fast tempo productions in a carrier sentence contexts. The results indicate that: (1) syllabic onset ...

There are many applications for which we would like to be able to track the ‘beat’ of a piece of recorded music – analogous to a listener’s foot-tapping. This paper describes our beat-tracking system, which operates by first estimating a global tempo (via autocorrelation of an ‘onset strength’ signal), then using dynamic programming to find the best sequence of beat times through the whole piec...
