Yes, there are contemporary poets who perform their work while accompanying themselves with a stringed musical instrument, in a tradition inspired by ancient Greek lyric. One notable example is the American singer-songwriter and poet Sappho (b. 1951), whose work is heavily influenced by the ancient Greek poet of the same name. Sappho is known for her performances in which she plays the guitar, lyre, or psaltery while reciting or singing her poetry. Her music is characterized by its ethereal, folk-like melodies and its poetic lyrics that often explore themes of love, loss, and nature.
