Is it considered ‘cheating’ if we incorporate the Candy Bars material into the Rhythm Template exercises? There’s some great material in the Candy Bars and I sometimes struggle to come up with interesting lines for the Rhythm Templates.
Using pre-written lines would defeat the purpose of the RTs. They are meant to exercise your mind and ears to learn to use the various concepts taught in the context of a progression.
If you like the lines in the Candy Bars, I suggest you try to write various etudes where you organize them in the context of a progression such as the blues. Just make sure you voice lead properly at the point of chord transition.
