An improved musical instrument string is pro- vided. The string (18) includes a polymer cover (26) that protects the string (16), from contamination while maintaining the original "lively" sound of the musical string. By supplying the cover (26) over a conventional string (16) and preferably over a conventional wound string, the string (16) is protected against contamination while also making the string easier to play. The pre- ferred cover comprises at least one layer of expanded polytetrafluoroethylene (ePTFE) that is most preferably sealed with a polymer coating. In particularly preferred embodiments, a cover is applied over a portion of the length of the string having a relatively reduced variable mass. The result is that the string has relatively uniform mass along its entire length thereby assuring correct in- tonation.

L'invention porte sur une corde améliorée d'instrument de musique. Cette corde (18) comporte une enveloppe polymère (26) protégeant la corde (16) de la contamination tout en lui conservant le son "vif" d'origine de la corde de musique. En disposant cette enveloppe (26) sur une corde classique (16) et, de préférence, sur une corde classique enroulée, on la protège de la contamination tout en la rendant plus facile d'emploi. L'enveloppe préférée, selon l'invention, comprend au moins une couche de polytétrafluoroéthylène expansé (PTFE) qui est de préférence isolée à l'aide d'un enduit polymère. Dans des réalisations particulièrement préférées, l'enveloppe recouvre une partie de la longueur de la corde, d'une masse variable relativement réduite. Il en résulte que la corde possède une masse relativement uniforme sur toute sa longueur, ce qui garantit un ton correct.
