Debussy wrote a sonata for flute, viola, and this instrument, and the violas are divided into two sections during the second movement of Mozart's concerto for this flute and this instrument. One notably challenging part for this instrument is found in Symphonie Fantastique, and the second movement of that piece contains crescendoing measures of rising triplets played on this instrument near the beginning. At the start of (*) Saint-Saens' Danse Macabre, it is strummed 12 times to symbolize a clock tolling midnight. This instrument is closely related to a zither, which has strings across the soundbox rather than attached to it at an angle, and by definition this instrument has either two or three sides. For 10 points, name this instrument which often has 47 strings
