Vocal style

Gaye had a four-octave vocal range. From his earlier recordings as member of the Marquees and Harvey and the New Moonglows, and in his first several recordings with Motown, Gaye recorded mainly in the baritone and tenor ranges. He changed his tone to a rasp for his gospel-inspired early hits such as "Stubborn Kind of Fellow" and "Hitch Hike". As writer Eddie Holland explained, "He was the only singer I have ever heard known to take a song of that nature, that was so far removed from his natural voice where he liked singing, and do whatever it took to sell that song."

In songs such as "Pride and Joy", Gaye used three different vocal ranges—singing in his baritone range at the beginning, bringing a lighter tenor in the verses before reaching a gospel mode in the chorus. Holland further stated of Gaye's voice that it was "one of the sweetest and prettiest voices you ever wanted to hear". And while he noted that ballads and jazz was "his basic soul", he stated Gaye "had the ability to take a roughhouse, rock and roll, blues, R&B, any kind of song and make it his own", later saying that Gaye was the most versatile vocalist he had ever worked with.

Gaye changed his vocal style in the late 1960s, when he was advised to use a sharper, raspy voice—especially in Norman Whitfield's recordings. Gaye initially disliked the new style, considering it out of his range, but said he was "into being produce-able". After listening to David Ruffin and Levi Stubbs, Gaye said he started to develop what he called his "tough man voice"—saying, "I developed a growl." In the liner notes of his DVD set, Marvin Gaye: The Real Thing in Performance 1964–1981, Rob Bowman said that by the early 1970s, Gaye had developed "three distinct voices: his smooth, sweet tenor; a growling rasp; and an unreal falsetto." Bowman further wrote that the recording of the What's Going On single was "...the first single to use all three as Marvin developed a radical approach to constructing his recordings by layering a series of contrapuntal background vocal lines on different tracks, each one conceived and sung in isolation by Marvin himself." Bowman found that Gaye's multi-tracking of his tenor voice and other vocal styles "summon up what might be termed the ancient art of weaving".
