Why is the sound of a harp soft in comparison with the sound of a piano?
Step 1 of 3 The piano get its sound ,when we hit the keys of the piano they move a hammer which then strikes a short string which vibrates to make the musical sound. Sound on the harp is produced by plucking the strings. The finger plucks the string, setting it into vibration. This wave of vibration travels down the string to the wooden soundboard where it is amplified. Step 2 of 3 The plucked strings of a harp are amplified a little by the small soundboard and acoustic cavity of the harp. The energy of a sharply struck piano key is much greater that the harpist's plucking and the sound board in the piano is much larger because There is more tension in the strings of a piano than in the strings of a harp.As such, the strings of a piano can be struck with more force than the strings of a harp, creating a louder sound.
