The krachappi (Thai: กระจับปี่, pronounced [kra.tɕàp.pìː]), also spelled grajabpi, is plucked, fretted lute of Thailand, used in central Thai classical music. It has four strings in two courses that are plucked with a plectrum and are constructed of teak or jackfruit wood. It can be played by holding the wand, which is composed of thin wooden planks, in your right hand and flicking the wires in and out while pressing the string with your left finger. Krachappi usually plays in a band called Mahori with four to eight instruments.
