A G minor concerto for two of these instruments was written by Antonio Vivaldi. (-5[1])Friedrich Grützmacher (“GROOTZ-mock-er”) arranged (-5[1])a B flat major concerto (-5[1])for this instrument to fit the style of a romantic concerto, one of twelve by Luigi Boccherini. Whilst playing between an E and an F sharp on one of these instruments, one might hear a wolf tone. (10[1])This is the highest of the two (-5[1])standard orchestral instruments to use thumb position. (10[1])Pablo Casals popularized a set of six suites for this instrument by J. S. Bach, (10[1])the first of which features a G (-5[1])major prelude. (10[1])Unlike other instruments in its section, this instrument is played sitting down with the aid of a spike. (10[2])For 10 points, name this string (10[1])instrument pitched between viola and double bass. ■END■ (10[4]0[1])
