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

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

    Sammanfattning : 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.

  3. 2. On the control of virtual violins : Physical modelling and control of bowed string instruments

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bowed string; physical modelling; sound synthesis; performance control; violin playing; Corde frottée; modélisation physique; synthèse sonore; contrôle gestuel; violon; Struken sträng; fysikalisk modellering; ljudsyntes; musikutförande; violinspel; Other physics; Övrig fysik; Computer science; Datavetenskap; Acoustics; Akustik;

    Sammanfattning :   This thesis treats the control of sound synthesis of bowed string instruments based on physical modelling. The work followed two approaches: (a) a systematic exploration of the influence of control parameters (bow force, bow velocity, and bow-bridge distance) on the output of a physical model of the violin, and (b) measurements and analyses of the bowing parameters in real violin playing in order to model and parameterize basic classes of bowing patterns for synthesis control.

  4. 3. The bowed string

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

    Sammanfattning : 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. LÄS MER
