Re: Hard to get rid of rest in Moeller Tech.
When You say 'rest' I'm assuming you mean you're using the moeller technique to play triplets and you can't do it without a rest between each triplet?
First, let me digress for a second. Moeller technique isn't triplets, it's the way you move your arm -a.k.a. the technique you use- to hit a drum. You can play singles (not talking about a single stroke roll here), doubles, triplets, rudiments -really, any sticking pattern with Moeller technique as long as there are accented strokes.
So, here's the thing. There are several interpretations of Moeller technique. If you watch Derrick Pope apply it, then watch Jim Chapin, then watch Dom Famularo, then watch Steve Smith or any of the others who use it and you'll see they all do it a little differently. But, the thing they all have in common is some sort of whipping motion. They may produce it in different ways, but that whipping motion is what you need to concentrate on in order to loose the 'rest' in between the triplets. Remember this -you said you tried altering your grip and loosening your fingers -but you need to zoom back the camera -the whipping motion involves your arm -all the way up to the shoulder in the method I was taught. An analogy that helps for all interpretations of moeller technique (at least, it helped me) is to think of your arm as a piece of rope. Now, think about whipping several waves through the rope. It's continuous and, if one end of the rope is your stick, notice that, as your stick is descending to strike the drum the other end of the rope is being lifted to form the next wave. Keep this image in your mind and try to recreate that flowing motion so that, as the stick is striking the drum, your arm is rising to form the beginning of the next wave -so, don't think of it like a series of movements, but one continuous flowing motion.
Spw's advice is pretty much right on. Also try exaggerating the whipping to the point of ridiculousness at first.
Seeing a teacher who knows this technique is best -hopefully this is helpful and not just confusing.
