How do you produce sound in fiddle?

Sound in a fiddle, or violin, is produced by drawing a bow across the strings, causing them to vibrate. The vibration of the strings is then amplified by the hollow body of the instrument. The pitch of the sound is determined by the string's thickness, tension, and length, which can be altered by pressing the strings against the fingerboard. Additionally, techniques like pizzicato (plucking the strings) or using harmonics can create different sound textures.
