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. (10[1])Whilst playing 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 instruments to use thumb position. Pablo Casals popularized (10[1])a set of six suites for this instrument by (-5[1])J. S. Bach, (-5[2])the first of which (-5[1])features a G major prelude. Unlike other instruments in its section, (10[1])this instrument is played sitting down with the aid of (10[1])a spike. (10[1])For 10 points, name this string instrument (10[1])pitched between viola and double (10[1])bass. ■END■ (10[5]0[1])
