The lyre has a few slightly different designs, though the original idea took from the single bow shape of a harp, replacing it instead with two pecheis (arms) joined with a zygos (crossbar) extending from a bowl-shaped sound box with kollopes (tuning pegs). The three-eleven chordai (strings), stretched across the crossbar and pulled down to the wooden soundboard but did not connect into the hollow body directly (much like a modern guitar, the strings run over a brudge).
In ancient Greece, the bowl shaped lyres used turtle shells, and the arms and pegs were made of either bone, wood, ivory, bronze or another metal. The strings were made using cow/sheep gut. Today, box and bowed lyres are wooden, and strings made of nylon are often used.
