A G minor concerto for two of these instruments was written by Antonio Vivaldi. (10[2])Friedrich Grützmacher (“GROOTZ-mock-er”) arranged a B flat major concerto for this instrument to fit the style of a romantic concerto, one of twelve by Luigi Boccherini. Whilst playing between an E (-5[1])and an F sharp on one of these instruments, one might hear a wolf tone. (-5[1])This is the highest of the two standard orchestral instruments to (-5[1])use (-5[1])thumb (-5[1])position. Pablo Casals popularized a set of six suites for this instrument by (10[1])J. S. Bach, the first of which features a G major prelude. Unlike other instruments in its section, this instrument is played sitting down with the aid of a spike. For 10 points, name this string instrument pitched between viola and double bass. ■END■ (10[4])
