What is the sound source in a harp?

In a harp, the sound is produced by the vibration of the strings. When a string is plucked, it vibrates and produces a ringing sound. The pitch of the sound produced depends on the tension of the string and its length. The tighter the string, the higher the pitch, and the longer the string, the lower the pitch. The strings of a harp are stretched between the soundboard and the neck, and the tension is adjusted by tuning pegs. When a string is plucked, it vibrates and transfers the vibrations to the soundboard, which amplifies the sound and projects it into the air.
