Quattro versioni originali della "Ritirata notturna di Madrid" is an arrangement by Luciano Berio of a movement from Luigi Boccherini's Musica notturna delle strade di Madrid.

The full title of the composition is Quattro versioni originali della "Ritirata notturna di Madrid" di Luigi Boccherini, sovrapposte e transcritte per orchestra (Four Original Versions from Luigi Boccherini's "Withdrawal by Night in Madrid", superimposed and transcribed for orchestra).

Berio decided to superimpose them with minor alterations to create a stratified sound structure.

The whole piece can be structured into one initial introductory section, in which a solo second violin and the drums indicate the ostinato rhythm, the theme, and eleven variations in which the melodies are further developed, which are followed by a final coda.

[3] The composition is scored for a large orchestra, consisting of three flutes, two oboes, one English horn, two clarinets in B-flat, one bass clarinet in B-flat, two bassoons, one contrabassoon, four French horns in F, four trumpets in C, three trombones, one bass tuba, timpani, a percussion section consisting of three percussionists playing two snare drums, one bass drum and one triangle, harp and a full string section.
