In the ex­am­ple shown in the last two steps be­low, I’ve used a tech­nique that em­ploys ‘stopped’ notes – ex­tremely short notes that don’t re­ally last long enough to con­vey any pitch in­for­ma­tion as such; they’re just rhyth­mic de­vices that em­u­late a bass player slap­ping a string with their thumb bone.


When a melody that pro­gresses in one di­rec­tion up or down the key­board is sup­ported by a bassline that moves in the op­po­site di­rec­tion, this is known as con­trary mo­tion. For ex­am­ple, take a chord

Eb, pro­gres­sion that plays Cm, and F, go­ing up in pitch, trav­el­ling to­wards the right end of the key­board. You might ac­com­pany this with a bassline that starts on C but pro­gresses down in pitch, trav­el­ling to­wards

Bb the left of the key­board to and A. You’ll find more about this idea in 206’s Easy Guide.
