It is said that the hills of Mizoram are alive with the sound of music. This strong sense of music and song of the Mizos has manifested itself in locally made musical instruments. One of these instruments is the ting-tong, a one-string Mizo musical instrument, which is very popular and commonly played, while some others like the traditional mithun horns, gongs and drums are only occasionally used. Preferences are changing, the guitar, locally made, is now very popular with the younger generation. Other Mizos instruments like the benz bung and the rewchhem (a long pipe) are no longer being used and very few Mizos know how to play them. Traditional ornaments of Mizoram include the thihus, a necklace with big amber beads, the thifen, a necklace with smaller beads, and the darthi, a necklace of glass beads. On special festive occasions Mizo women use a head gear called the vakiria. It consists of a bamboo band bedecked with a feather and decorated at the ends with beetle wings.
