   <dim:field mdschema="dc" element="description" qualifier="abstract" lang="en_US">Acoustic guitar musicians tune their instruments by using a conventional tuner. Individuals pluck the string and the conventional tuner indicates whether the note is sharp or flat. The musician then has to wind the string to increase the tension or loosen it to lessen it. This process can be very cumbersome and inefficient when performing under different weather conditions. This thesis provides the design process of the Automatic Acoustic Guitar Tuner which bypasses the musician and acts as its own feedback system. This new concept will reduce the time needed to tune a guitar by using an electromechanical design to wind and unwind the strings to eventually reach the desired frequency. The Automatic Acoustic Guitar Tuner will also increase the productivity in music classrooms which hold large number of students by reducing the tuning process.</dim:field>
