👉 A lithophone is a musical instrument that produces sound by vibrating a hollow, plastic tube. These tubes are often used to create the tone of bells or other instruments, and they can produce a wide range of sounds, from soft, melodic tones to harsher, more complex notes. The sound produced by a lithophone is typically heard through its vibrations, which can be detected using various types of audio equipment such as microphones, headphones, or even earphones.
