Pressing the valve with the thumb, open or close the bellows, accompanying this movement with the legs, everything very slowly. Doing it this way, you will not listen to the air that takes place when this action is made quickly. (Drawing 1). In lessons Nº 1, and until Nº 24, make it whenever you arrive at the double bar of compass. It is advised, in the first lessons, long notes in slow movements, observing that the emitted sound does not have vibrations. When it is executed closing, make pressure only with the thumb and not with the palm of the hand.
Position of the body in the chair
The back will have to be supported in the endorsement of the chair. The legs will have to stay in right angle, never with fall towards ahead. The feet in form more or less similar to when the needles of the clock mark ten past ten. (Drawings 2 and 3)
Position and state of the arms
The arms fallen and mainly relaxed, almost stuck to the body, doing angle with the elbow and without any tension.
Position of the hands
The wrists flexible and without tensions. The thumb of each hand supported on the superior end of the strap and without doing forced pressure. This aid to the necessary relaxation of the other fingers, that, when they press the keys, opening or closing, is necessary to accompany this movement with the legs.
Movement of the legs
The legs will have to accompany the movement by the instrument being opened and closed, treating that the going and coming does not cause vibrations in the sound. Do not mark the musical times with the feet. (Drawing N 3)
