"MacArthur Park" is a song by Jimmy Webb, originally composed as part of an intended cantata.
The song was first recorded by Richard Harris. The Harris recording of "MacArthur Park"
comprises four sections or movements:
A mid-tempo arrangement, called "In the Park" in the original session notes,
built around piano and harpsichord, with horns and orchestra coming in, accompanying
the song's main verses and choruses
At about two and a half minutes in, this shifts to a slow tempo and quiet arrangement
paired with an alternate lyric, "After the Loves of My Life"
At about five minutes in, a sudden switch to an up-tempo instrumental section, "Allegro",
led by drums and percussion and punctuated by horn riffs, building up to an orchestral climax
At about six and a half minutes in, a reprise of the first section's arrangement accompanying the final choruses and another climax.
