1. A sound-generating reed for a wind instrument which contains at least one thermotropic liquid crystalline polymer, wherein:
rod-like molecule chains of the at least one thermotropic liquid crystalline polymer of the reed (10) are oriented in a longitudinal direction, from a shaft (12) of the reed to a cutting edge-like front edge (14) of a tongue (16), and in that the tongue (16) has a wall thickness of ≤0.15 mm at the cutting edge-like front edge (14) thereof; and
proceeding from the cutting edge-like front edge (14), the tongue (16) comprises a wedge-shaped portion (18) having a planar upper face which has a small acute angle in a direction towards the shaft (12), and a constant wall thickness over a width of the reed (10).
