Even when you can get through the mazourka tolerably well, you must not think, on that account, that you will be able to play it in company, under trying circumstances.

You ought to be able to play the piece by yourself with ease, very frequently, perfectly, and distinctly, and in very rapid _tempo_, before you trust yourself to perform it even slowly in company.

At least, practise the more difficult passages for the right hand very frequently, particularly the difficult and bold conclusion, that it may not strike the hearer as rough, weak, tame, or hurried.

It is an old rule, "If you begin well and end well, all is well." You ought to practise the skipping bass over and over again by itself, otherwise it will not go.

An incorrect or deficient bass, without depth of tone and without accentuation, ruins every thing, even the good temper of the hearer.
