    2. A reed according to claim 1, wherein the reed has a water absorption of 0.1% by weight to 2% by weight, according to ISO 62.

    3. A reed according to claim 1, wherein the polyamide is selected from the group consisting of PA 6.12, PA 6.10, PA 6.11, PA 10, PA 12, PA 11, PA 9-T, PA 10.10, PA 11, PA 12.12.

    4. A reed according to claim 3, wherein the polyamide is selected from the group consisting of PA 6.12, PA 6.10, PA 6.11.

    5. A reed according to claim 1, further comprising one or more additives.

    6. A reed according to claim 5, wherein the reed comprises 22 to 40% by weight of the one or more additives.

    7. A reed according to claim 5, wherein the one or more additives include glass fibres.

    8. A reed according to claim 1, wherein the reed is composed only of the polyamide and glass fibres.

    9. A reed according to claim 8, wherein the proportion of glass fibres is in amounts up to 40% by weight, wherein the remainder is the polyamide.

    10. A reed according to claim 1, wherein the reed is a single reed or a double reed.

    11. A mouthpiece for a wind instrument, comprising the reed according to claim 1.

    12. A wind instrument, comprising the reed according to claim 1.

    13. A method of manufacturing a reed for reeds for wind instruments, comprising forming a polyamide into a reed, wherein the polyamide is of the group: PA a, PA b.c, or PA d-T or a mixture (blend) thereof, wherein a≥10, b≥6, c≥10, d≥9.

    14. A reed according to claim 2, wherein the reed has a water absorption of 0.7% by weight to 0.8% by weight, according to ISO 62.

    15. A reed according to claim 9, wherein the proportion of glass fibres is between 22% and 40% by weight, wherein the remainder is the polyamide.

    16. A wind instrument, comprising the mouthpiece according to claim 11.

    Description

    [0035] FIGS. 1a and 1b show water absorption data of reeds made from PA 6.6.

    [0036] FIGS. 2a and 2b show water absorption data of reeds made from PA 6.12.

    [0037] In FIG. 1a to 2b there is shown the water absorption of reeds made from polyamides. FIGS. 1a and 1b show reeds made from PA 6.6 with glass fibre additives, whereas FIGS. 2a and 2b show reeds made from PA 6.12 with glass fibres. In the respective upper diagram (FIG. 1a or 2a, respectively), there is shown the conditioning at 80° C., wherein there may be seen that the water proportion absorbed will remain constant already after a short period of time.

    [0038] In the respective lower diagram (FIG. 1b or 2b, respectively), there is shown the water absorption at 40° C. conditioning, which corresponds approximately to the environment of the reed within the musician's mouth. Also here, there is realized for a short term a higher water absorption, which will eventually, however, remain constant.

    [0039] In the case of PA 6.6 with glass fibre additives, the maximum water absorption at 80° C. was up to 2.82% by weight. In the case of PA 6.12 with glass fibre additives, however, the water absorption at 80° C. was at the most 0.70% by weight.

    [0040] For this reason, the musician may grind and process these products similarly to the wooden reed, and as soon as he/she puts it into his/her mouth, they will absorb a certain moisture proportion, similar to the wooden reed, which will remain constant after short play-tuning. Similarly, this condition may be pre-simulated by way of conditioning. A low moisture absorption is decisive for a high sound quality, as it renders the material elastic when vibrating and thus gets closest to the common behaviour of a wooden reed.

    [0041] In the case of PA 6.12 the weight increase is between 0.05 and 0.70% by weight. This material, hence, is more stable, creating more constant ratios in comparison to PA 6.6. The data of PA 6.10, PA 6.11, PA 10 or PA 12, which are comparable to those of PA 6.12, are not shown.
