The "o" is an open string and "x" indicates that the string is unplucked. The numbers 1, 2, and 3 indicate finger position, but is irrelevant for this lab. In order to acoustically simulate a guitar chord go the Online sequencer web-page. By default the sequencer uses the electric piano as the instrument. Change this to a guitar clicking on the arrow and selecting an Acoustic Guitar. Next use Figure 2 below to determine the notes corresponding to your assigned guitar chord. C T a A G E D Once all the notes have been determined, enable them on the sequencer such that they all play at the same time. The sequencer will continue to loop through the chord continuously. Use MATLAB to record the a sample of the guitar and determine the frequencies within the chord from the spectrum. Deliverable: A plot of the spectrum, a list of notes for the assigned chord, and a list of the corresponding frequencies within the chord. oo. 0000
