In many areas of Tibet, singing is at the wedding. The singers may come from the groom's family, or the bride's family, or even be the guests. There are also often some special singers commissioned. Some of them may be the Lamas. Whatever they are, they are skilful at singing. Since the singing is a part of the wedding ceremony, the singers must follow some rules. For example, in Rotug of Ngari (Ali) Prefecture, there is a book, named Wedding Songbook of Rotug, which has been handed down, and specially used on wedding for ages.

Some people say that this songbook originated in the time when Princess Wencheng had just arrived in Tibet, and married to the Tubo King Songtsan Campo; but some others say it has a history of no more than one or two hundred years. Yet in any case, it has provided fixed procedures of singing on weddings in Rotug. The subjects of the songs in this book cover so broad a range that perhaps few persons could know them all by heart. Even the special singers have to carry it all along for handy reference. There are 31 parts in the book, dealing with diversified subjects, such as the color arrow, deity, guest, snow berg, rock, door, and highland barley wine, etc, some of which serve as the background melody accompanying certain ceremonies, such as the colored arrow presenting, the ceremonial scarf offering, the acknowledging farewell and the coronal taking, etc; and some of which are sung over and again, for example, the coronal, colored arrow, farewell and etc.

The singing is significant for time of opening the wedding ceremony. More accurately speaking, the time when the bride can be fetched vests in the talent of the singer commissioned by the groom's family. According to the local customs, this singer is in fact the special envoy for the bride-fetching, who shall pass three barriers to get to the bride's home. The first and second barriers are set respectively on the way to the bride's home; while the third one is just out of the bride's house. When the messenger sent by the bride's family meets the singer half way, the former will present the latter a ceremonial scarf and a cup of highland barley wine. Now it is time for the singer to give full play to his talent. If he does not perform well, he will fail to pass the barrier. Occasionally, some singer even fails for a straight 10 or 20 days, until the messenger shows mercy, by asking the singer to offer a ceremonial scarf instead. Yet the last barrier ahead is much difficult to pass.
