"I don't know how he's doing it on the drums... but I do know how to do it on the turntables!" 

Qbert recorded a new lesson with some simple ways to get melodic in your drum skratching. Originally inspired by hearing how drummers can create melodies with their drum kits by hitting different notes, Qbert breaks it down in skratch terms. 

Find it from the Lessons Menu -> Skratching -> Level 5 -> "Melodies in Drumming".
