Trumpet in C and piano - difficult - Digital Download SKU: S9.Q11691 Wo die schönen Trompeten blasen. Composed by Stefan Heucke. This edition: Sheet music. La Tromba. Downloadable. Op. 56. Duration 15 minutes. Schott Music - Digital #Q11691. Published by Schott Music - Digital (S9.Q11691). The famous Wunderhorn song 'Wo die schönen Trompeten blasen' by Gustav Mahler forms the musical background of this work commissioned by the trumpet player Griseldis Lichdi. Heucke's one-movement trumpet sonata of approximately 15 minutes' duration plays constantly with the approaching of and distancing from Mahler's original. Elements of the sonata form, multi-part song and free variation forms combine to form a many-faceted and exciting rhapsody.
