As early as October 1968 at
TTG Studios in Hollywood, California, Hendrix began recording demos for a song titled "The New Rising Sun". Although it is substantially a different song, Hendrix biographer John McDermott believed that "Hey Baby" was developed from ideas found in "The New Rising Sun". In the months following the TTG sessions, Hendrix attempted more recordings of the song at the
Record Plant in New York City. Preliminarily titled "Hey Gypsy Boy" and "Hey Country Boy", they were closer to "Hey Baby" musically and lyrically. Hendrix used a minor-key chord progression reminiscent of "
All Along the Watchtower", but they lacked the distinctive guitar intro section to "Hey Baby". In February 1970, Hendrix jammed on an informal "Hey Baby" at the Record Plant, with drummer
Buddy Miles and percussionist
Juma Sultan. Hendrix sang the song live and included some Spanish
flamenco-style flourishes on electric guitar. After parting ways with Miles, Hendrix began preparing songs with original
Jimi Hendrix Experience drummer
Mitch Mitchell and
Band of Gypsys bassist
Billy Cox, for the upcoming
The Cry of Love Tour. McDermott described Cox's and Mitchell's approaches as "delicate interplay... more subtle and intricate", which was needed for
R&B-influenced songs, such as "Hey Baby". The trio debuted the song at the
Forum in Los Angeles on April 25, 1970. Unlike the later studio version, Hendrix begins the song with solo guitar reminiscent of "the acoustic-guitar introductions found in Spanish flamenco music as, unaccompanied, Hendrix explores
arabesques and
altered scales", according to music writer Keith Shadwick. The solo guitar became a regular feature of Hendrix's live performances of "Hey Baby" and its length varied to suit his mood and the audience reaction. Hendrix chronicler
Harry Shapiro described Hendrix's guitar sound as having a "pitch and sway like waves gently rolling against a deserted sandy beach in early morning". During late-1969 and 1970, Hendrix was making extensive use of a
Uni-Vibe guitar
effects unit, which is able to emulate the wavering
chorus- and
tremolo-effects of a
Leslie speaker. This effect had previously been used on the demos for "The New Rising Sun". Writers Dave Whitehill and Dave Rubin commented: "the thick chorusing does give it a lot more cohesiveness and depth [which a dry or straight sound would lack] it's very effective in the introduction, where the guitar has to carry the full musical weight itself." "Hey Baby" is composed of an intro section and a main section with a
bridge. The intro is one of the longest in a Hendrix song, lasting 51
measures. In the intro, Hendrix takes a
chromatic approach with guitar runs and chords at a moderately slow tempo of 66
beats per minute (bpm). After several key and
time signature changes, he lands on
A minor, which begins the chord progression at a somewhat faster tempo of 81 bpm for the remainder of the song: A minor–G–F–D. Lyrically, "Hey Baby" echoes a recurring Hendrix theme of an idealized feminine figure, as heard in "
May This Be Love", "
Little Wing", and "
Angel". Journalist
Charles Shaar Murray felt that the figure goes beyond "Hendrix's own personal saviour, but [as] a redeemer for all of humanity". Shapiro also described the hope of "a promised land, a new beginning": Poet
David Henderson called the R&B-style bridge section or
refrain, which begins with "Girl, I'd like to come along", "the essence of the lyrics of this deceptively straightforward song". ==Recording and studio releases==
