As it is better in the absence of good coaches to do many drills (but not TR0, 1, 2, 3, 4) with the student solo, mocking up the session as he goes, we are using this at Saint Hill.
A student, many of whom feel the emptiness of the empty chair he or she is facing, should make or buy and use a doll.
The doll need not be elaborate but should be at least a foot tall, preferably two feet.
The drills of spitting out rapidly Model Session Repetitive Rudiments, Fast Rudiments, Listing, Nulling, etc, are at this time being done coachless and great progress is being made.
But the empty chair”gets” some auditors. Therefore the doll. Dolls were used in training first in 1957.
