Why should you wish to attract attention, and to create an effect by foppishness and all sorts of grimaces, or by curious and marvellous exhibitions of _virtuoso_-ship?
You have only to play musically and beautifully, and to deport yourselves with modesty and propriety.

Direct your whole attention to the business in hand,--that is, to your performance; and endeavor to secure for it the interest of the public, who are so easily rendered inattentive.

We want no more public performances from eccentric geniuses.

Do not devote yourself exclusively to pieces calculated to show the skill of the performer.

Why desire always to show off your power in octave passages, your trills, your facility in skips, your unprecedented stretches, or other fantastic feats?
You only produce weariness, satiety, and disgust, or, at least, you make yourselves ridiculous.
