The Corelli Alliance strings are the result of know-how in the process of the composite fibres. We are the only manufacturer having been able to adapt the Alliance KF fibre for making musical strings for different instruments (guitar, lute, harp, violin, viola and now cello). To reach such a point we had to solve a certain number of technological problems inherent to the nature of the Alliance KF material and worked through the complex processes necessary to give it the characteristics desired in top quality strings. Although Corelli Alliance strings are made of a composite core of synthetic material, they present all the sound qualities and characteristics which are found in the best gut strings with additional significant advantages over gut strings. For all these reasons Corelli Alliance strings represent the best alternative to gut strings, which nobody could expect.
