A bit of history
The lyre (from Latin "lyra", and this from the Greek "A") is a primitive string instrument, shaped like an abacus, the origin of which was attributed to Hermes or the muse Polimnia. It was the musical instrument that Orpheus played and accompanies Apollo as a symbol of the citizen state, culture and music.
The lyre is a musical instrument that, like the harp, was played with both hands.
In the hands of David, the poet and wise king, the lyre evokes union with divinity and religion. King David played the lyre to reassure Saul.
The descendant instruments of the lyre are the zither, the guitar and the latud, which continue the tradition of lyre to this day as the instruments of the poet and the troubadour.
Dyehuty is the god of wisdom, writing, music and the Moon, in Egyptian mythology, related to music as the inventor of the lyre.
