Because of the quality of both their strings and rosin, PIRASTRO has become the byword for a sound which is both beautiful and reliable. As a result, a great number of string musicians play and recommend PIRASTRO strings. With their tonal flexibility and expressive power, PIRASTRO strings have inspired musicians to create their own unique sound by taking full advantage of their instruments best qualities. Each individual string in the PIRASTRO line has been meticulously crafted to provide musicians with an unsurpassed choice in tonal colors. Musicians can choose from the complete range of gut strings (e.g. Passione and Oliv) to synthetic strings (such as Evah Pirazzi and Tonica) or steel (e.g. Flexocor and Chromcor). Finally, PIRASTRO rosins are designed specifically for use with PIRASTRO strings and this combination is responsible, in no small part, for the excellent world-renowned PIRASTRO sound.
