A G minor concerto for two of these instruments was written by Antonio (10[1])Vivaldi. 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 (-5[1])between an E and an F sharp on one of these instruments, one might hear a wolf tone. This is the highest of the two standard orchestral (-5[1])instruments to use thumb position. (-5[1])Pablo Casals popularized (10[1])a set of six suites (-5[1])for this instrument by J. S. Bach, (10[1])the first (-5[1])of which features a G (10[1])major prelude. Unlike other instruments in its section, this instrument is played sitting down with the aid of a spike. (10[1])For 10 points, name this string instrument pitched between viola and double bass. ■END■ (10[3])
