 "Piggies" features baroque musical elements in its melody and texture. Music journalist Steve Smith groups the song with the Paul McCartney-written "For No One" and "She's Leaving Home" as examples of the Beatles' forays into baroque pop. Harrison biographer Simon Leng recognises the composition as essentially a folk song, however, that was then given a "satirical, drawing-room [musical] arrangement" on the official recording through the prominence of harpsichord and orchestral strings.
