At under thirty seconds, this track is one of the shortest pieces ever released by a major act, yet it rewards close study. Its brevity is deceptive: every moment is intentional, and there is no filler to hide behind. Learning it means learning to make each note count.

Paul McCartney recorded this as a solo acoustic performance for Abbey Road, released in 1969. It was originally cut as part of the medley on the album's second side, then removed, then accidentally left at the very end of the record by an engineer. McCartney decided to keep it, making it one of the earliest known hidden tracks in rock history.

The feel is a bright, strummed acoustic shuffle in a two-beat pulse. The harmony is straightforward, moving through common diatonic chords with confident, unhurried momentum. The form is so compact that the song is essentially a single verse with an abrupt, unresolved ending. That ending, a chord left hanging, is a deliberate compositional choice and one of the most discussed musical jokes in the catalog.

When approaching this piece, focus on committing fully to the short form. There is no room to warm up or recover. Practice entering confidently, maintaining an even rhythmic pulse throughout, and trusting the silence at the end. It is an excellent exercise in economy and presence, two qualities that transfer to every instrument and every genre.
