Violin: When the bow is dragged along the strings of a violin a sound is produced. Depending on which strings are touched, different sounds, pitches, and tones are produced. Without the instrument, a similar sound is produced, but it does not have the same amount of depth or is as easily heard. The stretching of the strings and the hollowness of the instrument allows the sound to be more fluid with a greater amplitude, and therefore, a louder sound.
