Prominent examples include:

• Claude Debussy's Beau soir (1880), Prélude à l'après-midi d'un faune (1894), Nocturnes (1899), La Mer (1905), La cathédrale engloutie, "Voiles", "Feuilles mortes"
• Maurice Ravel's Daphnis and Chloë Suite No. 2 (1913), "Menuet" from Le Tombeau de Couperin
• Erik Satie's ''Le Fils des étoiles (1892)
• Igor Stravinsky's The Rite of Spring (1913)
• Olivier Messiaen's music features abundant planing
• Richard Strauss's Elektra (1909)
• Arnold Schoenberg's Pierrot lunaire, "Columbine" (1914)
• William Schuman's Three Score Set for Piano (1944)
• John Williams's "Rebel Fanfare" from Star Wars

In the Schuman example (Three Score Set for Piano), the inversions of the chords suggest a bichordal effect.Kliewer, Vernon (1975).

In the example on the top right, we see a series of quartal chords in parallel motion, in which the intervallic relationship between each consecutive chord member, in this case a minor second, is consistent. Each note in the chord falls by one semitone in each step, from F, B{{music|flat}}, and E{{music|flat}} in the first chord to D, G, and C in the last.
