   Författare :Anders Elowsson; Anders Friberg; Pawel Herman; Anders Askenfelt; Gerhard Widmer; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Music Information Retrieval; MIR; Music; Music Transcription; Music Perception; Music Production; Tempo Estimation; Beat Tracking; Polyphonic Pitch Tracking; Polyphonic Transcription; Music Speed; Music Dynamics; Long-time average spectrum; LTAS; Algorithmic Composition; Deep Layered Learning; Convolutional Neural Networks; Rhythm Tracking; Ensemble Learning; Perceptual Features; Representation Learning;

   Sammanfattning : This dissertation presents ten studies focusing on three important subfields of music information retrieval (MIR): music transcription (Part A), music perception (Part B), and music production (Part C).In Part A, systems capable of transcribing rhythm and polyphonic pitch are described.

3. 2. Why so different? - Aspects of voice characteristics in operatic and musical theatre singing : Aspects of voice characteristics in operatic and musical theatre singing

   Författare :Eva Björkner; Anders Askenfelt; Ronald C. Scherer; KTH; []
   Nyckelord :HUMANIORA; HUMANITIES; operatic singing; musical theatre singing; voice source; subglottal pressure; flow glottogram; inverse filtering; formant frequencies; amplitude quotient AQ ; Music; Musikvetenskap;

   Sammanfattning : This thesis addresses aspects of voice characteristics in operatic and musical theatre singing. The common aim of the studies was to identify respiratory, phonatory and resonatory characteristics accounting for salient voice timbre differences between singing styles. LÄS MER

4. 3. On the beat : human movement and timing in the production and perception of music

   Författare :Sofia Dahl; Anders Askenfelt; David Huron; KTH; []
   Nyckelord :HUMANIORA; HUMANITIES; Music; Musikvetenskap;

   Sammanfattning : This thesis addresses three aspects of movement, performance and perception in music performance. First, the playing of an accent, a simple but much used and practiced element in drumming is studied, second, the perception of gradually changing tempo, and third, the perception and communication of specific emotional intentions through movements during music performance.

5. 4. On the control of virtual violins : Physical modelling and control of bowed string instruments

   Författare :Matthias Demoucron; Anders Askenfelt; Rene Causse; Benoit Fabre; Marcelo Wanderley; KTH; []
   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.

7. 5. 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.
