“A Change of Heart” is the title track of David Sanborn’s 1987 album, which “reached #74 on the Billboard 200, #43 on Billboard’s R&B Albums chart and #3 on the Top Contemporary Jazz Albums chart.” (SessionDays).
“By the mid 1980s, saxophonist Sanborn’s sound was dominated by the synthetic tinge of keyboards and synthesizers, falling in line with the slick, crossover jazz style of the era,” (JazzAtelier). “Change of Heart is emblematic of Sanborn’s direction at the time, and its eight tracks alternate between funky, danceable numbers and smooth ballads, all with a highly polished commercial veneer.” Crossover was something of a code word for the more frequently used term smooth jazz, a genre which peaked in the 80s and could easily be found on the FM dial in most major North American cities at that time. AllMusic describes the genre as “an outgrowth of fusion, one that emphasizes its polished side.”
The track begins with a melodically acrobatic intro led by a panpipe-like patch on a wind-controlled (“EWI”) synthesizer, a new development in synthesis. The EWI player was one of the instrument’s foremost players and boosters, tenor saxophonist Michael Brecker, who also used the instrument on some of his own material. The tune begins in earnest as a slow funk groove kicks in at the 0:50 mark, alternating between A minor and its relative C major. At 1:14 – 1:38, there’s a shift into Eb lydian mode and then a return to the original A minor/C major. A quick revisit to the intro’s territory from 2:25 – 2:50 brings a dialogue between Brecker’s birdsong-like EWI lines and Sanborn’s trademark jump-to-lightspeed sonic intensity. At 4:02, a late kitchen-sink bridge kicks in, led by Marcus Miller’s driven stepwise descending bass lines and a saturation of every possible square inch with multiple synth textures and compound harmonies. But at 4:24, the groove falls away and the intensity dissipates for the outro as Brecker’s darting EWI sound is once again the focus.
