This is the first edition of virtuoso guitarist and composer J. K. Mertz’s Divertissement über Motive der Oper: Der Prophet (Meyerbeer), Op. 32 since its original publication in 1851. The work is a charming selection of themes from Giacomo Meyerbeer’s opera Le prophète expertly arranged for violin or flute, viola, and guitar. It is of moderate difficulty and represents Mertz’s only known extant work for this instrumentation. The present edition includes biographies of Mertz and Meyerbeer, suggestions concerning performance practice, and both a facsimile and an urtext edition of this long out-of-print chamber work.
