In the first place, the proper basis for a firm structure is wanting.

The knowledge of the notes cannot afford a proper basis, except in so far as it is of service in the execution of a piece.

Of what use are the notes to a singer, if he has no attack, and does not understand the management of the voice?
of what use to the piano-learner, if he has no touch, no tone on the piano-forte.
