Bowed Violin String is Perfect

The Bowed Tube: a Virtual Violin

This paper presents a virtual violin for real-time performances consisting of two modules: a violin spectral model and a control interface. The interface is composed by a sensing bow and a tube with drawn strings in substitution of a real violin. The spectral model is driven by the bowing controls captured with the control interface and it is able to predict spectral envelopes of the sound corr...

A Methodology for Investigation of Bowed String Performance Through Measurement of Violin Bowing Technique

What is a proper start of a bowed string?

The onset of a note on a bowed instrument shows a transition period during which the periodic "steady-state " motion develops. Depending on the particular combination of bowing parameters, this state is often characterised by periods which are prolonged ("delayed triggering1>, or by a division of the period into two or several parts ("multiple flyback "). An onset with perfectly periodic motion...

Elementary Stability Considerations for Bowed-String Motion

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...
