{{Short description|1875 waltz by Johann Strauss II}} '''Cagliostro-Walzer''' op.370 is a [[waltz]] by [[Johann Strauss II]] composed in 1875 based on themes from his [[operetta]], [[Cagliostro in Wien]] which premiered on 27 February 1875 at the famous [[Theater an der Wien]].
The waltz principal melody was based on the waltz duet "Könnt' ich mit Ihnen fliegen durchs Leben" or 'Could I but fly with you through life' sung in Act 2 of the operetta. The operetta itself was a success at its first performance and Strauss long adopted the practice of opera composers to draft melodies from their successful stage works to be arranged as a new piece to boost sales of sheet music, thus he composed this 'Cagliostro-Walzer'.
The entire waltz consists of just 3 two-part waltz sections which is also a new Strauss development from the previous 5 two-part sections heard in his earlier works. The piece began with a loud march melody in the [[C major]] key before progressing into waltz time. The principal waltz theme in C major is also in the style of [[The Blue Danube]], where three notes in rising melody starts off the waltz proper. Waltz 2A carries the principal key in C major as well but quickly interpolates with a more thoughtful passage in [[E-flat major]]. Waltz 3A starts off in [[F major]] in a hesitant mood, proceeding into a climax with [[cymbal]]s. A brief [[coda (music)|coda]] enters and the entire Waltz 2B is repeated. After a short chorded passage, the swirling Waltz 1A recurs and Strauss signs off the waltz with a strong chord and long snare-drumroll.
