You will succeed after a while, but precipitation, compulsion, and disputes are useless.

The improvement of a soprano voice, ruined by over-screaming, requires prudence, patience, calmness, and modesty, and a character of a high type generally.

It is also a very thankless task, and success is rare; while on the piano a fair result may always be accomplished.
* * * * * I return once more to the subject so frequently discussed, that I may try to relieve the universal difficulty of our lady pianists.

I have heard much playing of late, in parties both small and large, on well-tuned and on ill-tuned pianos, on those with which the performer was familiar, and on those to which she was unaccustomed; from the timid and the self-possessed; from ladies of various ages, possessed of more or of less talent, and in various cities: the result was always the same.
We hear from the ladies that they could play their pieces at home before their parents or their teachers; but this is never sufficient to enable them to save their hearers from weariness, anxiety, and all sorts of embarrassment.

My honored ladies, you play over and over again two mazourkas, two waltzes, two nocturnes, and the Funeral March of Chopin, the Mazourka and other pieces by Schulhoff, the Trill-Etude, and the Tremolo by Carl Meyer, &c.: "it makes no difference to you which." You might be able to master these pieces pretty well, but, instead of this, you yourselves are mastered.
