It is well known that most of the classical instruments we have today, Amati, Stradivari and Guarneri, but also most of the production by minor authors have progressively and radically been altered since the second half of the eighteenth century.  All instruments of the classical period had in fact constructive and tonal characteristics totally different to those of today, starting with the strings going on to crucial elements such as projection and assembly of the neck, the shape of the fingerboard, of the bass bar including accessories such as the bridge, the pegs and the tail-piece Since 1960ies increased attention has been paid to rediscovering the playing criteria of the seventeenth and eighteenth centuries with a consequent request to the violin-making world for instruments following as faithfully as possible the original constructive conception of the baroque period.  Therefore S&Z also includes this necessity with the construction of instruments reflecting antique making methods: the neck not inclined, nailed to the upper block, laminated fingerboards and tail-pieces, bass-bars and accessories made following the tradition of the baroque period. Similarly as for the playing, also a philological reconstruction of the instruments always implies a margin of interpretation both due to the scarcity of  direct sources and above all owing to their extreme variability in time and geographical area.  Bearing this in mind, it is particularly important to adopt solutions which are not only historically correct, but which satisfy the necessities of today’s philological interpretation especially under the aspect of sound. The offer of instruments is not limited to the panorama of the seventeenth century and of the early eighteenth century, but also includes the transition period of the second half of the 18th century, thanks to the study of original findings particularly going back to the production method of Giovanni Battista Guadagnini.  Moreover the workshop accepts orders for instruments belonging to the family of the viola da gamba, or special ones such as the viola d’amore, mandolins, etc.
