Tubular Bells was recorded on an Ampex 2-inch 16-track tape recorder with the Dolby noise-reduction system, which was the Manor's main recording equipment at the time.[7] Oldfield had Virgin hire instruments including guitars, keyboards and percussion instruments.[15] Oldfield has recounted differing stories over the years regarding the inclusion of the tubular bells; in 2001 he suggested that they were among the instruments he asked Branson to hire,[6][16] but in 2013, he said that he saw them among the instruments being removed from the studios after John Cale had finished recording there, and asked for them to be left behind.[17]

Oldfield recorded side one, known as "Opus One" at the time, during his one allotted week at the Manor in November 1972.[7] He was particularly interested in starting the piece with a repeating riff, and devised the opening piano sequence after experimenting with an idea for several minutes on Bedford's Farfisa organ. He wanted a slight variation on its 16/8 time signature by dropping the sixteenth beat, and chose the key of A minor as it was easy to play. Oldfield recorded the opening riff on a Steinway grand piano, but struggled to perform in time. Heyworth solved the problem by placing a microphone next to a metronome in another room and feeding it into Oldfield's headphones.[18] The short honky-tonk piano section was included as a tribute to Oldfield's grandmother, who had played the instrument in pubs before World War II. The staff and workers at the Manor made up the "nasal choir" that accompanies it.[7] Oldfield had difficulty in producing a sound from the tubular bells, as he wanted a loud note from them but both the standard leather-covered and bare metal hammers did not produce the volume that he wanted. In the end, Newman obtained a heavier claw hammer and Oldfield used it to produce the desired sound intensity but cracked the bells in the process.[25]
