The current study investigated the human ability to synchronize movements with event sequences containing continuous tempo changes. This capacity is evident, for example, in ensemble musicians who maintain precise interpersonal coordination while modulating the performance tempo for expressive purposes. Here we tested an ADaptation and Anticipation Model (ADAM) that was developed to account for...

An approach of parsing piano music interpretation is presented. We focus mainly on quantifying expressive timing activities. A small number of different expressive timing behaviors (constant, slowing down, speeding up, accent) are defined in order to explain the tempo discretely. Given a MIDI performance of a piano music, we simultaneously estimate both discrete variables that corresponds to th...

We approach a specific scenario in real-time performance following for automatic accompaniment, where a relative tempo value is derived from the deviation between a live target performance and a stored reference, to drive the playback speed of an accompaniment track. We introduce a system which combines an online alignment process with a beat tracker. The former aligns the target performance to...

This paper presents a rhythm recognition technique based on a probabilistic approach by utilizing generative model for timing information in expressive music performance. The problem of rhythm recognition including rhythm parsing and tempo tracking, is to retrieve information of rhythm and tempo from a sequence of observed note durations. Since performed note length deviates in real performance...

Adaptation to tempo changes in sensorimotor synchronization is hypothesized to rest on two processes, one (phase correction) being largely automatic and the other (period correction) requiring conscious awareness and attention. In this study, participants tapped their finger in synchrony with auditory sequences containing a tempo change and continued tapping after sequence termination. Their in...

The research described here focuses on global tempo transformations of monophonic recordings of saxophone jazz performances. 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. That is, listeners should not be able to notice, from the expressivity of a performance, that has been scal...

Speech tempo (speaking rate) varies both between and within speakers. Previous research suggests several relevant factors and predictors. The present study investigates all these factors combined, both between and within speakers, in a large corpus of spoken Dutch interviews. This is done by means of multi-level modeling of sex, age, and dialect region (all between speakers) and phrase length a...

Christopher Raphael Department of Mathematics and Statistics University of Massachusetts, Amherst [email protected] Abstract A method is presented for the rhythmic parsing problem: Given a sequence of observed musical note onset times, we simultaneously estimate the corresponding notated rhythm and tempo process. A graphical model is developed that represents the evolution of tempo and rhy...

Interaction with human musicians is a challenging task for robots as it involves online perception and precise synchronization. In this paper, we present a consistent and theoretically sound framework for combining perception and control for accurate musical timing. For the perception, we develop a hierarchical hidden Markov model that combines event detection and tempo tracking. The robot perf...

The song of a male zebra finch is a stereotyped motor sequence whose tempo varies with social context--whether or not the song is directed at a female bird--as well as with the time of day. The neural mechanisms underlying these changes in tempo are unknown. Here we show that brain temperature recorded in freely behaving male finches exhibits a global increase in response to the presentation of...
