Rhapsody was originally a Greek strolling minstrels, the rhapsodists, pre- rendered poem or part of a seal. Today is meant by Rhapsody a vocal or instrumental work is not tied to any particular form in music. The musical themes of the rhapsody are regularly connected loosely with each other, they can be volatile, disjointed motifs which do not necessarily build on each other or are entangled. Usually the themes and motifs come from the folk music. Rhapsodies were, inter alia, by Johannes Brahms, Claude Debussy, Maurice Ravel ( Rhapsodie Espagnole ), George Gershwin ( Rhapsody in Blue ), George Enescu (Romanian Rhapsodies ), Antonín Dvořák ( Slavonic Rhapsody ), Ralph Vaughan Williams (Norfolk Rhapsody ) and Franz Liszt ( Hungarian Rhapsodies ) published.
The Liszt's rhapsodies are based on so-called Gypsy Airs, whose main feature is the so-called Gypsy minor scale with a minor third, excessive fourth, sixth, and major seventh smaller. However, Liszt took into account in his compositions prevailing in the salons of his day taste in music. Rachmaninoff has with the "18 Variation - Rhapsody " a style appropriate to his interpretation of the term delivered on a Theme of Paganini.
In Bohemian Rhapsody, the mold was taken up by the rock band Queen.
