The term 'classical instrument' refers to instruments that have been used in classical music for centuries. Two examples of such instruments are the LYRE and the OBOE. The LYRE is a stringed instrument that has been used since ancient times, and is often associated with Greek mythology. The OBOE is a woodwind instrument that was developed in the 17th century and is known for its distinctive sound. Both the LYRE and the OBOE are still used in classical music today.
