“Acquaforte” is the italian word for “etching”.
Etching is a chalcographic technique with which a metal plate is engraved and then immersed in an acid, which will be used as a mold. In my composition, the solo violin has precisely an "engraving" function, we could say a role of trigger towards the string orchestra, the latter in fact always plays in reaction to the solo violin, filling the grooves caused by its mordant.
