We are particularly honoured to deal with our 22nd acoustic test in this review, devoted to contemporary violin making . After our first “tests” on some interesting violas and cellos, we have lately focused our attention on violins. For example, the talented violinist Anastasiya Petryshak played a brand-newly made instrument by Lorenzo Cassi. Anastasiya Petryshak was born in Ivano-Frankivsk, Ukraine in 1994. She started studying the violin when she was 8 thanks to her music teacher Marta Kalynchuck. She moved to Italy at 17, after graduating with honours. She is currently attending Walter Stauffer Music Academy and Monteverdi Institute in Cremona, together with “Accademia Chigiana” in Siena. At Monteverdi Institute she has been studying with Salvatore Accado, O. Semchuck and L. Gorna. Since 2010 she has been playing both as a soloist and as a duo with Andrea Bocelli in several concerts. She is also interested in contemporary music: she has been a member of modern and contemporary music ensemble “Fontana Mix”since 2012. She regularly performs at concerts, not only as a soloist but also with internationally famous musicians. Our new audition was centred on a “ 1705 Stradivari” model made by Lorenzo Cassi. This violinmaker from Pianello Val Tidone got his diploma at International Violinmaking School in 1997, under the guidance of Vincenzo Bissolotti who taught him the violinmaking technique. Cassi makes exclusive use of Cremonese “inner mould” classical method; he carries out threading literally following Bissolotti’s teachings who, in turn, refers to Simone Ferdinando Sacconi’s work. This did not prevent Cassi’s work from being personal: curvings, f-holes, tips, scroll and varnish are peculiar of Cassi's. He worked for 4 years at Francesco Bissolotti’s workshop and specialized in making violins, violas and cellos. In 2001 he opened his own workshop, together with his wife Kathrin. His work shows both elegance and precision. Cassi revises not only the models belonging to classical Cremonese violinmaking school (Antonio Stradivari, Giuseppe Guarneri del Gesù , Andrea and Nicolò Amati)) but also to Brescia School (Gasparo da Salò) and the Venetian one (Domenico Montagnana) The violin tested and played by Anastasiya Petryshak was made in 2013. The spruce of the front displays a lot of tappings; the back is in a two-piece spruce wood with very tight but long and deep veining. The handmade thread is in black- dyed pear tree wood and in white poplar wood . While the Adagio of Sonata No. 1 BMW 1001 by J.S. Bach was being played, the acoustic features of the instrument stood out: it is easy to play thanks to impeccable fitting, with good dynamics; it is also powerful and rich of tones.
