Debussy used his memories of England as inspiration for the music, in addition to the song "Dansons la gigue" by Charles Bordes[2] and the Tyneside folk tune "The Keel Row",[3] which are used as key themes.

Richard Langham Smith has commented on Debussy's own wish to incorporate ideas of juxtaposing elements of the visual arts in musical terms,[6] including a quote from Debussy to Caplet from a letter of 26 February 1910: "You can't imagine how naturally the transition works between 'Parfums de la nuit' and 'Le Matin d'un jour de fête.

"[7] Matthew Brown has briefly commented on Debussy's use of techniques such as incomplete progressions, parenthetical episodes, and interpolations in Ibéria.

Debussy had already quoted the song Nous n'irons plus au bois in Images oubliées of 1894 for piano and in Jardins sous la pluie from Estampes (1903).
