 After recording the second version of the song , Lennon wanted to do something different with it , as Martin remembered : " He 'd wanted it as a gentle dreaming song , but he said it had come out too raucous . He asked me if I could write him a new line @-@ up with the strings . So I wrote a new score ( with four trumpets and three cellos ) and we recorded that , but he didn 't like it . " Meanwhile , on 8 and 9 December , another basic track was recorded , using a Mellotron , electric guitar , piano , backwards @-@ recorded cymbals , and the <unk> ( or <unk> ) , an Indian version of the zither . After reviewing the tapes of Martin 's version and the original , Lennon told Martin that he liked both versions , although Martin had to tell Lennon that the orchestral score was at a faster tempo and in a higher key ( B major ) than the first version ( A major ) . Lennon said , " You can fix it , George " , giving Martin and Emerick the difficult task of joining the two takes together . With only a pair of editing scissors , two tape machines , and a vari @-@ speed control , Emerick compensated for the differences in key and speed by increasing the speed of the first version and decreasing the speed of the second . He then spliced the versions together , starting the orchestral score in the middle of the second chorus . ( Since the first version did not include a chorus after the first verse , he also spliced in the first seven words of the chorus from elsewhere in the first version . ) The pitch @-@ shifting in joining the versions gave Lennon 's lead vocal a slightly other @-@ worldly " swimming " quality .
