Peter Yates, Professor of guitar in the Department of Music, will show some of the results of his recent investigations into the arpeggione (19th-century bowed guitar) in a concert at 4pm on Sunday Feb. 1st in the organ studio. He has had to build his own instrument (cruelly sacrificing a beautiful baby cello and a serviceable guitar) to do this. The result has been an instrument capable of playing items from the viola-da-gamba repertoire (featured will be a Bach sonata and a solo piece from the Dutch Baroque), as well as bowed versions of works for guitar (in this case, two pieces by 20th-century-Mexican composer Carlos Chavez).
