“Improving Musical
Expressiveness by Time-Varying Brightness Shaping”

Sound examples 1: Effects of the mouth pressure on clarinet timbre
Sound 1 : series of synthesized
clarinet tones corresponding to increasing values of the mouth pressure and
fixed reed aperture.
The brightness and loudness of the tones increase as the mouth pressure
increases.
Sound examples 2: Effects of the embouchure on clarinet timbre
Sound 2a : “normal” timbre (classical
mouthpiece configuration)
Sound 2b : “narrower” timbre (obtained
by taking much less mouthpiece)
Sound 2c : “twisted” timbre (obtained by
taking too much mouthpiece)
Sound examples 3: Relation between timbre and sound level
Sound 3 : clarinet crescendo performed by
trying to keep a stable timbre
Sound examples 4: Timbre Material / Timbre Temporal Shape
Sound 4a : original
clarinet tone
Sound 4b : resynthesized tone with a fixed Spectral Centroid value (corresponding to the onset of the original
tone)
Sound 4c : resynthesized tone with a fixed Spectral Centroid value (corresponding to the offset of the original
tone)
Sound examples 5: Time-varying brightness shaping
Bach’s Suite II excerpt (Allemande)
Sound 5a : expressive clarinet
performance (Clh1)
Sound 5b : piccolo flute sampler-based performance
(Pic0)
Sound 5c : piccolo flute performance
after the time-varying brightness shaping (Pic1)
Sound examples 6: Reversing the tones’ brightness variations
Sound 6a : sampler-based clarinet
performance with expressive brightness variations
Sound 6b : sampler-based clarinet
performance with reversed brightness variations
