Famous for its use in the film 'Barry Lyndon', this sarabande is a profound example of Baroque dance form. Its gravity and noble melancholy are expressed through harmonic depth and stately, rhythmic emphasis.
Executing the ornamentation fluidly within the heavy, chordal texture is the primary technical challenge.
