How to play the lyre?

Modeling structure and playing method of the lyre.

Traditional woodblock New Year pictures are mostly made of a whole piece of Sang Mu, mahogany, walnut or sandalwood, and the length is 1 m.. The piano box is like a cut half-gourd, with a diamond-shaped upper part and an oval abdominal cavity in the lower part, which is covered with goatskin or roebuck skin. There is a crescent-shaped sound hole on the diamond panel, a pine sound column is placed between the back of abdominal cavity and the leather membrane, and seven vertical lines are engraved on the back of piano. The head of the piano is engraved with a dragon head carving, which is also called the dragon head piano by the people. There are three shafts on both sides of the chord groove. The piano is slender and hollow, with fingerboards, frets and six strings attached to the front end. The wooden mill has always maintained a quaint shape, and some piano bodies are composed of upper and lower sections. Folk humorously call the upper part mother and the lower part father. When playing, most of them sit on the floor or chair, the piano box is tilted on the right leg, the piano head is tilted to the left, the left hand holds the piano to press the strings, and the right hand holds the pick to play.
