There's another type of sandwich that happens when you play. This one is probably mostly happening for you if you're already counterbalancing, but it's helpful to visualize it specifically.
Procedure:
- Sniff and Toss
- Feel how your shoulder blades are down in back, supporting your arms, so that your hands are just floating up in front of you. Your left hand is floating there in the air. As long as you're counterbalancing in back, that left arm/hand will be able to float up there with no more work on your part.
- Drop a finger onto the fingerboard. Notice that the fingerboard just happens to be sandwiched between your floating arm and your dropping finger. It isn't holding up your finger, nor is it being held up by your hand and arm. It's just there in the middle.
- Feel that balance between your floating arm and your fingers dropping. As you drop a finger, it is balanced by your floating arm -- too much force and it will disturb your fingerboard. You want to drop each finger just enough that it still remains in balance with your floating arm. The fingerboard just happens to be in the middle of this balancing act. This is the Fingerboard Sandwich.
