Check out this video of Shakatak playing their Nightbird

Here’s the transcription of the piano solo on Nightbird:

Again, we see the application of Forward Motion theory in this solo transcription.

According to Hal Galper and his Forward Motion theory,

“A chord is spelled out by synchronizing the strong beats (the “on” beats) of the bar with the strong tones (chord tones) of a chord scale, and the weak beats (the “off” beats) with the weak tones (non-chord tones). ”

For more detail discussion on this, read this article on Tension and Release Beat

Keeping this in mind, observe the scale run at bar 7 of the solo transcription, here’s a snapshot:

Immediately we see the effect of the B natural note circled. By placing it where it is, all the chord tones from a Cm7 chord are beautifully alligned with the relatively stronger beats of the bar.

Had the chromatic passing tone be added somewhere else, a weaker melody line would be heard.
