How can I keep from singing?

Wilhelm Ganz (1833-1914) was a German musician who escaped from the continent in 1848 and spent the rest of his life in London. As a violinist and conductor he worked alongside Berlioz and Wagner and held a singingprofessorship at the Guildhall School of Music. Despite being well-regarded in his lifetime his compositional work has largely fallen into obscurity over the last century.Ganz’s Op.12 is Qui Vive(c.1860-70): inspired by the Galop a lively country dance but intended for concert performance. It is scored for a Piano Duet and keeps the pianists entertained by modulating several times through closely linked keys based around Eb Major.
