Answer 2

The answer is echo

Explanation:

• In acoustics, reverberation, often called reverb, is the persistence of sound, or echo, after a sound is made.

• An echo is a reflection of sound that comes to the listener with a delay after the direct sound in audio signal processing and acoustics. The delay is exactly proportional to the separation between the source and the listener of the reflecting surface.
• The redirection of a wave as it travels through one medium and into another is called refraction. Changing the medium or the wave's speed can both result in a redirection.
• In diffraction, a sound wave is bent or spread out in a single medium where the sound speed is constant.

Therefore echo is required to make music melodious.
