"Blackbird" is a Beatles song from double-disc album The Beatles (also known as The White Album). It was written by Paul McCartney, and is played by Paul Mc Cartney on a Martin D 28 acoustic guitar and features recordings of a blackbird singing. The tapping sound on the track, which some people think is a metronome, is McCartney tapping his feet on the hard studio floor.
