The composition and its arrangement suggest a relaxing sea setting, with cymbals imitating the sound of waves (Mick Fleetwood played his drum kit using timpani mallets to give a muted sound) and a dreamy solo from Green's guitar. It contains four chords, E, Emaj7 (or G#m/E), A/E, and F#m, played by Green on his Fender Stratocaster into a Matamp Series 2000. Green had been working on the piece for some time before the addition to the band of 18-year-old guitarist Danny Kirwan. Slide guitarist Jeremy Spencer was not generally inclined to work with Green, who had felt unable to realise the overall effect that he wanted. With Kirwan's input, Green completed the piece and it was recorded just two months after Kirwan joined, without Spencer present. Although he was not a part of the recording sessions, Spencer was shown in video material miming to Green's slide guitar parts. Kirwan's instrumental "Jigsaw Puzzle Blues" was chosen for the B-side in most territories. "Albatross" has been re-released many times as a single in various countries, with many different B-sides.
