Among the distinguishing features of the arrangement is an echo-laden "clip-clop" percussion part, sleigh bells played on every beat, and a low-range melodic phrases played on flute during the latter sections of the song. A strip of masking tape was placed over the strings of a piano while the bottoms of two plastic orange juice bottles were used for percussion. Singer Danny Hutton was present at the session, as he recalled, " would hear something wrong, and bam 'One more time.' I just sat there and didn't say a word. I had been in sessions where I thought to myself, they should do this and that. Not this time. I just shut up. What could I add?" Bruce Johnston, who joined the band a year earlier, later said that he "didn't realize just how great" "Pet Sounds" was going to be until he witnessed this session.
