There are three things to consider in the art of singing — First, sentiment; second, voice; third, execution. Sentiment and voice are chieﬂy the gift of nature. Study can develop and strengthen them, but it cannot give them to one who is entirely destitute of them. Execution can be acquired and perfected, with more or less labor, according to the aptness of the individual. As before singing well it is necessary to sing in some manner, we shall have to occupy ourselves, at first, with the voice and with its mechanism. We shall afterwards speak of musical sentiment, and of the proper means for developing it.
