Stringed instruments, such as a guitar or bass, are an application of transverse string vibrations. A music note is essentially sound of a specific frequency. As the string is plucked, it vibrates at its natural frequency, causing the surrounding air to vibrate at the same frequency and creating a musical note. In music, a scale is any set of musical notes ordered by their fundamental frequency and pitch and an octave is an interval whose higher note has a fundamental frequency twice that of its lower note. A scale dividing a C-C octave into twelve notes is shown below. Starting from the lower C note, the interval is evenly divided in terms of its frequency so each successive frequency is 2(1/12) times frequency of the previous note, and so that the fundamental frequency of the higher C is twice that of the lower C. The neck of the guitar (fretboard) contains metal slots called frets, and the fretboard is used by holding down the strings against each fret and then plucking them. The vibrating motion of the string against the metal frets create the sounds of different musical notes, and the fretboard is designed so that the notes created by each subsequent fret follow a standard musical scale. 1. Briefly describe the role of each component in determining the note that a string produces from a vibrational standpoint: a. The fretboard. b. The tuning pegs. c. The bridge. 2. Briefly explain why the frets are unevenly spaced along the guitar neck. 3. Using your knowledge of string vibrations and from a practical standpoint, explain the design justification of practical standpoint, explain the design justification of having more than 1 string on a guitar4. From a vibrational standpoint, how does this technique change the sound produced by the string?
