Roller Coaster Ride!
A Snakey, Chromatic ii-V7 Line
The original exercise was made up of a pattern which, connecting each measure by a half step, repeated itself down a perfect 4th, and which can be found on pp. 71-76 of my eBook, "Slick Licks That Stick!" which is available right here.
The downloadable exercise presented here is my attempt to tonicize and resolve the original line. Probably the easiest and most accessible way to do that, in my estimation, was as.......you guessed it; some sort of ii-V7-I resolution.
