“…The shape of the mouthpiece strongly influences the vibrations of the reed. In recent years major progress has been made in the development of synthetic materials to replace reeds which are traditionally made out of natural cane [6]- [9]. To better understand the interaction between the mouthpiece and the reed, it is necessary to obtain data on reed vibration patterns and to perform dynamic measurements of strain distribution during the vibration cycle.…”

In this paper, we present a study of different optical textures and techniques to apply very fine, non-specular reflecting random speckle texture, which makes it possible to measure surface strains with a sensitivity better than 0.01 % strain on a vibrating object. The method is based on triggered stroboscopic digital image correlation, which is able to obtain time-resolved full-field measurements of displacement and strain fields. The method is demonstrated on reeds of the saxophone to investigate their role in sound production and playability. Such high-sensitivity measurements allow the detection of subtle effects, such as artefacts on synthetic saxophone reeds caused by the production process.

“…[1][2][3][4] The reed consists of a material with elastic fibres along its length and which is thinned towards the tip. [5][6][7] The player places the lower lip on the reed, and both lips form an airtight seal around the mouthpiece. The force of the lower lip bends the reed towards the mouthpiece.…”

Single-reed musical instruments, such as the saxophone, generate sound through a complex interplay between the mechanics of the reed and the hydrodynamic and acoustic pressure in the instrument mouthpiece. To understand this complex mechanism, experimental data are lacking. This paper presents full-field, time-resolved measurements of strain and displacement of a vibrating saxophone reed, measured under mimicked realistic playing conditions. It is found that strain along the length axis of the reed is mainly expansive, except in a small zone near the tip where it becomes compressive when the reed touches the front edge of the mouthpiece. At the instant in the vibration phase where the reed touches the mouthpiece, significant bending and compressive strain appear along the direction perpendicular to the reed axis. Strain magnitudes in both directions are similar, with absolute values of 0.1%. Fullfield strain maps reveal subtle characteristics which are not revealed by displacement measurements. Bi-axial bending and strain may be an essential component in reed mechanics, which up till now has been fully neglected in modelling.

“…Significant investigations related to the mechanical resistance of Phragmites stands were performed in [ 18 , 19 , 20 ]. Indeed, the elasticity of cane reeds was measured in previous studies using a three-point bending testing setup in order to obtain the mechanical properties along the direction of the reed fibers and in the orthogonal direction [ 21 ].…”

The search for sustainability has led to the utilization of more ecological materials with at least, a similar structural performance to those used at present. In this regard, reed fits the environmental and structural requirements as it is a sustainable and biodegradable lignin-cellulose material with remarkable mechanical properties. This research confirms the reed’s structural efficiency as it demonstrates that it has excellent strength and stiffness in relation to its density. The reed anisotropy has a large impact on its properties. Indeed, the strength and stiffness parallel to the fibers are clearly higher than in the perpendicular direction. The results confirm that strength and stiffness decrease with the moisture content and nodes act as reinforcement in compression and bending. If compared with steel, timber and concrete, the reed possesses the highest value for strength. Hence, reed constitutes a strong candidate for environmentally friendly engineering.
