The Supremes’ “You Keep Me Hangin’ On” (1966) is “a brisk, urgent, desperate song, and it absolutely snaps into gear the second we hear that itchy morse-code guitar riff panning between speaker channels … (Stereogum). “‘You Keep Me Hangin’ On’ sounds easily 10 years ahead of its time, and listening to it, you can immediately hear why Diana Ross thrived in the disco era while so many of her ’60s peers flailed.
‘You Keep Me Hangin’ On’ was Holland-Dozier-Holland’s attempt to write a rock song … The guitar, from Funk Brothers ace Robert White, is foregrounded, going back and forth between that ticcing intro and deep, resonant strums. The drums and percussion work together in lockstep, pushing forward the song’s urgency. The bassline is another James Jamerson wonder, busy and complicated but never so showy that it detracts attention from the rest of the song … Holland-Dozier-Holland parted ways with Motown soon afterward, only giving the Supremes one more #1 after ‘You Keep Me Hangin’ On.’ As it turns out, the Supremes were fine without them. But listening to this, it’s still hard not to wonder what might’ve happened if they’d stuck around, if their genius had even more time to develop within that peerless Motown thrill-delivery system.”
The form starts with the chorus in Ab minor. As the tune shifts into the first verse at 0:36, B major (with a big emphasis on a compound A/B chord) goes into effect; the major key feels restful by comparison, not least due to the lack of the percolating “news bulletin theme” guitar part that skitters over the top of the rest of the tune.
