  2. 1. Development of Helmholtz motion and related wave patterns in the bowed string

    Author : Knut Guettler; KTH; []
    Keywords : ;

    Abstract : Of the many wave patterns that the bowed string is capableof producing, the so-called‘Helmholtz motion’(Helmholtz 1862) gives the fullest sound in terms of power andovertone richness. Papers one and two of this thesis deal withthe creation of this particular string movement: The firstpaper, based on computer analysis, describes some systemparameters’influence on the transient in terms of‘playability’.

  4. 2. The bowed string

    Author : Knut Guettler; KTH; []
    Keywords : Bowed string; violin; musical acoustics; musical transient; anomalous low frequencies; Helmholtz motion;

    Abstract : Of the many waveforms the bowed string can assume, theso-called "Helmholtz motion" (Helmholtz 1862) gives the fullestsound in terms of power and overtone richness. The developmentof this steady-state oscillation pattern can take manydifferent paths, most of which would include noise caused bystick-slip irregularities of the bow-string contact. READ MORE

  5. 3. Mechanics and acoustics of violin bowing : Freedom, constraints and control in performance

    Author : Erwin Schoonderwaldt; Anders Askenfelt; Knut Guettler; Jim Woodhouse; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; bow-string interaction; bowed string; violin playing; motion capture; bowing parameters; performance control; Other physics; Övrig fysik; Music; Musikvetenskap;

    Abstract : 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 bow-bridge distance), but imposing constraints as well.
