How will the harp make sounds of a different volume?

The volume of sound produced by a harp can be varied by changing the force with which the strings are plucked. Plucking the strings more forcefully will produce a louder sound, while plucking them more gently will produce a softer sound. Additionally, the volume of sound can be affected by the length of the strings, with shorter strings producing a higher volume than longer strings. Finally, the type of material used for the strings can also influence the volume of sound, with metal strings producing a louder sound than nylon strings.
