In addition, you will practise industriously every thing which we have gone through, especially the first variation; but you must always do it with interest, and never with weariness.

Of course you will practise _without notes_ all the little exercises for the touch, and for the fourth and fifth fingers, and the cadences.
_Third Lesson._ Other little exercises; trills, scales with shading for one hand alone and for both together; the skipping basses, &c.

We will begin to-day with the bass part of the second variation.

You observe that often there are even eighth notes in the treble, while in the bass there are even triplet eighth notes.

In order to play these properly together, even with only mechanical correctness, it is necessary that the left hand shall acquire a perfectly free and independent movement, and shall bring out the bass with perfect ease.
