The physics of wound and unwound strings on the electric guitar are presented here, and the pitch intervals produced by the movements of a Fender Stratocaster tremolo unit are explained. Predicted changes in pitch sensitivity of different strings are given, and experimentally verified, for changes in saddle height, the distance of string free to move behind the nut and ratio of diameters/masses...

Periodic or quasi-periodic low-frequency components (i.e. vibrato and tremolo) are present in steadystate portions of sustained instrumental sounds. If we are interested both in studying its expressive meaning, or in building a hierarchical multi-level representation of sound in order to manipulate it and transform it with musical purposes those components should be isolated and separated from ...

In this paper we present a new vibrato and tremolo suppression technique for onset detection. It weights the differences of the magnitude spectrogram used for the calculation of the spectral flux onset detection function on the basis of the local group delay information. With this weighting technique applied, the onset detection function is able to reliably distinguish between genuine onsets an...

Sonification--representing data in sound--is a potential method for supporting human operators who have to monitor dynamic processes. Previous research has investigated a limited number of sound dimensions and has not systematically investigated the impact of dimensional interactions on sonification effectiveness. In three experiments the authors investigated accuracy for identifying changes in...

This paper resumes the results of a research conducted in a music production situation Therefore, it is more a final lab report, a prospective methodology then a scientific experience. The methodology we are presenting was developed as an answer to a musical problem raised by the Italian composer Marta Gentilucci. The problem was “how to extract a temporal structure from a vowel tremolo, on a t...

This paper proposes a novel and effective approach to extract the pitches of the singing voice from monaural polyphonic songs. The sinusoidal partials of the musical audio signals are first extracted. The Fourier transform is then applied to extract the vibrato/tremolo information of each partial. Some criteria based on this vibrato/tremolo information are employed to discriminate the vocal par...

Energy separation algorithms using Teager's energy operator have been used to analyze modulations in speech resonances, and energy separation in bird song. Here we apply energy separation and the energy operator to the analysis and resynthesis of musical instrument sounds. We show how the energy operator can be used to (a) examine vibrato and tremolo (b) precisely determine frequencies of harmo...

Tremolo is a technique to produce the same note continuously in short spans, and an important for musical performance on mandolin. However, it not easy beginners master this technique, nor even expert players perform wide range of expressions. There no unified view proper behavior tremolo playing, there are examples measured behavior. In study, we hand movements during playing One test subject ...

In the multi-channel tape piece With Shifting Joints, I composed instrumental articulations and placed them around the listener. I applied virtual instruments, physical models comprised of cells and their connections. Such instruments allowed me to realise unconventional articulations with high precision and extreme parameter changes. For example, I bowed an instrument with such a sharp attack ...
