Spain

Corea wrote it, in 1971 by Wikipedia and in 1972 by some other sources. It closes Light as a Feather at 9:51, from the IBC London sessions of October 8 and 15, 1972. It opens with the adagio of Joaquin Rodrigo's Concierto de Aranjuez (1939), then moves into a fast steady samba-like rhythm, with improvisation chords based on Rodrigo's harmonies. Corea told the Barcelona Metropolitan that he fooled around with that theme, extended it and composed melodies that turned out to be the main themes of Spain, that Gil Evans had arranged the Aranjuez second movement on Sketches of Spain, and that he always plays Rodrigo's second movement as a keyboard intro. Wikipedia says Paco de Lucia was an inspiration, which is unsourced there.

The Light as a Feather version was nominated for two Grammys, Best Instrumental Arrangement and Best Instrumental Jazz Performance by a Group, and Corea won the 2001 Grammy for Best Instrumental Arrangement for Spain for Sextet and Orchestra. NPR listeners ranked it 23rd in a poll of the top 100 jazz songs. He recorded it again with the Akoustic Band (1989), with Bobby McFerrin (1990), as solo piano (2000), with the London Philharmonic on Corea.Concerto (2001), with the Elektric Band at Montreux in 2004, with Hiromi and on Trilogy (2013). Setlist.fm lists it 25 times on Corea's stats page.
