In normal woodwind tone production the nonlinear flow control properties of the reed transfer energy among the harmonics of the spectrum, and the favored playing frequency is one for which the air column input impedance is high at several harmonics. Above the middle of the second register, woodwinds have only one participating impedance peak; yet these notes can be played even without the use of a register hole, despite competing possibilities of low register intermode cooperation. Such notes…

Hidden influence of resonators for non-linear oscillators
Many self-sustained oscillators of musical interest consist of two resonators coupled by a nonlinear oscillating flow control orifice. Examples include musicians playing reed woodwinds or brass
Regeneration in brass wind instruments
This paper is concerned with the production of musical notes by the interaction between the lips of a player and a brass wind instrument. The mechanism of this non-linear oscillation, together with
Interaction of reed and acoustic resonator in clarinetlike systems.
TLDR
Analytical approximations of the oscillating solution based on Fourier series expansion are obtained in the vicinity of the threshold of oscillation, allowing to emphasize the conditions which determine the nature of the bifurcation through which the note may emerge, with therefore important consequences on the musical playing performances.
Investigation of bassoon embouchures with an artificial mouth
Playing double-reed woodwinds in tune requires individual embouchure adjustments for each fingering. By pressing his lips to the opposing reed blades, the musician can fine-tune the amplitude and
Acoustic properties of a reed (Arundo donax L.) used for the vibrating plate of a clarinet
The effect of water-soluble extractives on the acoustic properties of a reed (Arundo donax L.) used for the vibrating plate of a clarinet was investigated at various relative humidities (RH). At low
Aerodynamic excitation and sound production of blown-closed free reeds without acoustic coupling: the example of the accordion reed.
TLDR
The accordion reed is an example of a blown-closed free reed and the sound is found to be dominated by the dipolar source associated by the strong momentum fluctuations of the flow through the reed gaps, which leads to velocity fluctuations in the reing opening and then to an unsteady Bernoulli force.
Nonlinear characteristics of single-reed instruments: quasistatic volume flow and reed opening measurements.
TLDR
It is shown that the reed stiffness and the ratio of the effective surface of the jet and the reing opening are constant in a large range of openings.
Measurement of vocal-tract influence during saxophone performance.
TLDR
Vocal-tract influence is clearly demonstrated when pitch bending notes high in the traditional range of the alto saxophone and when playing in the saxophone's extended register.
Differences and similarities in the production mechanism of reeds, brass, and voice: the source-filter viewpoint
The acoustic sound production mechanisms of reed instruments, brass instruments as well as of the human voice (singing and speech) are already well investigated. In this paper these mechanisms will
Discrete-time modelling of brass and reed woodwind instruments with application to musical sound synthesis
TLDR
The main bulk of the thesis describes methods for linear modelling of the instrument air column using a travelling-wave based approach, which allows for dynamic and intuitive control of the musically important simulation parameters.
