Some aspects of bow resonances - conditions for spectral influence on the bowed string

نویسنده

  • Anders Askenfelt
چکیده

The dynamics of the frictional force between the bow hair and the string causes the bow to oscillate in its longitudinal direction during the bow stroke. Under certain conditions, such oscillations in the bow enhanced by the bow resonances can be observed in the spectrum of the frictional force between bow and string, and also in the velocity spectrum at the bridge. The present study discusses the necessary conditions for such an interaction to be noticeable. Further, the influence of bridge resonances on the spectrum of the Ji.ictiona1 force is examined. The analysis is based on computer simulations in combination with observations on real bows and strings, when played by a bowing machine.

Mechanics and acoustics of violin bowing Freedom, constraints and control in performance

This thesis addresses sound production in bowed-string instruments from two perspectives: the physics of the bowed string, and bow control in performance. Violin performance is characterized by an intimate connection between the player and the instrument, allowing for a continuous control of the sound via the main bowing parameters (bow velocity, bow force and bowbridge distance), but imposing ...

Influence of Attack Parameters on the Playability of a Virtual Bowed String Instrument

The transient behavior of a virtual bowed string is measured under different conditions of bow-force and bowvelocity onset. The results are compared with the constant-force, constant-velocity case, and with published physical measurements made using a bowing machine. Issues related to “playability” of virtual bowed-string instruments are discussed.

Torsional waves in a bowed string

Bowing a string with a non-zero radius exerts a torque, which excites torsional waves. In general, torsional standing waves have higher fundamental frequencies than do transverse standing waves, and there is generally no harmonic relationship between them. Although torsional waves have little direct acoustic effect, the motion of the bow-string contact depends on the sum of the transverse speed...

Influence of attack parameters on the playability of a virtual bowed string instrument: tuning the model

In this paper, we test the hypothesis proposed in a companion paper submitted to this conference (see [SS00]), namely that the playability of a bow stroke can be fully described by three parameters bow velocity, bow position and bow force. Moreover, the envelope of these parameters influences the quality of the attack. In this paper, we present a novel technique for measuring parameters of bowi...

Violin bow vibrations.

The modal frequencies and bending mode shapes of a freely supported tapered violin bow are investigated by finite element analysis and direct measurement, with and without tensioned bow hair. Such computations are used with analytic models to model the admittance presented to the stretched bow hairs at the ends of the bow and to the string at the point of contact with the bow. Finite element co...
