Lewisohn writes that 1965 introduced the part of the Beatles' career where they put less focus on live performances and took "a more serious application in the recording studio."{{Sfn|Lewisohn|1988|p=54}} He identifies multiple new [[Recording practices of the Beatles|recording practices]] used on ''Help!'', one being "to rehearse songs with a [[Tape recorder|tape machine]] running, spooling back to record properly over the rehearsed material."{{Sfn|Lewisohn|1988|p=54}} Another involved adding numerous [[Overdubbing|overdubs]] to rhythm tracks without considering them as comprising new takes; because of this, many songs on ''Help!'' are documented as having needed only a small number of takes, yet they still required hours of work.{{Sfn|Lewisohn|1988|p=54}} Martin also began placing the guitar parts on different tracks than the bass and drums, accomplishing "a more satisfying stereo image" according to [[Walter Everett (musicologist)|Walter Everett]].{{Sfn|Everett|2001|p=281}}

According to Hertsgaard, ''Help!'' showed "a major acceleration in the Beatles' ongoing search for fresh sounds."{{Sfn|Hertsgaard|1995|p=128}} He points out that half of the songs feature instruments the Beatles had never used before, including [[electric piano]], flutes, a volume/tone [[Effects unit|pedal]], and most famously "Yesterday{{"'}}s strings.<ref>{{Harvnb|Hertsgaard|1995|p=128}}; {{Harvnb|Everett|2001|p=281}}: "volume/tone pedal".</ref> ''Help!'' is also the first Beatles album to feature the [[Epiphone Casino]], first purchased by McCartney around December 1964 before quickly becoming a staple of the group's instrumentation.{{Sfn|Everett|2001|p=282}} Before the recording of "Yesterday", the flutes on "You've Got to Hide Your Love Away" were played by [[John Scott (composer)|John Scott]], only the second outside musician to appear on a Beatles track (after [[Andy White (drummer)|Andy White]]).{{Sfn|Lewisohn|1988|p=55}}
