in a general sense, means the production of appreciable and varied sounds by the voice. In a more limited sense, it means different inflexions of the voice through intervals admitted in music, and consistent with the rules of melodic modulation. It is well known that these inflexions differ from those of the voice in speaking. In singing, harshness of vocal timbre (see Music), and falseness of intonation, are much more frequently met with than the opposite qualities, especially among persons not trained to sing. Musical training, when applied to a person possessed of a naturally good quality of voice, and a good ear, produces effects that can hardly be imagined by those who have not watched them attentively. Upon the subject of vocal-training, the reader may consult any of the best treatises on singing. For some remarks on the mechanism of the human voice in singing, and the compasses of voices, see Music.

SINAGLIA, a town of the Papal States, in the legation of Urbino, at the mouth of the Misa, in the Adriatic, 16 miles W.N.W. of Ancona. It is regularly, but not very strongly, fortified, with ramparts, bastions, and a citadel. The buildings, which are almost all modern, are generally good, and the streets broad, straight, and regular. There are a cathedral in the Corinthian style, in the form of a Greek cross, several convents, a mint, a theatre, and a small harbour. Sinaglia is celebrated for its annual fair, in the end of July and beginning of August. This has been established for several centuries, and attracts great crowds from all parts of Italy. The town occupies the site of the ancient Sena, surnamed Gallica, to distinguish it from the place of the same name, now Siena, in Etruria. It is infamous in history for the treacherous murder, in 1502, by Cesar Borgia, of several chiefs who were in alliance with him. Pop. 9000.
