The term 'Strings for Orpheus' refers to the LYRE, a stringed musical instrument associated with the Greek mythological figure Orpheus. The LYRE is believed to have been invented by Hermes and given to Apollo, who then gave it to Orpheus. The LYRE was used by Orpheus to charm animals and even stones with his music. It is also said that Orpheus used his LYRE to bring his wife Eurydice back from the underworld.
