Once you have gotten the basic idea, go to the folder on ELMS labeled "lab 10 audio data". Inside, you will nd mpSs of several different instruments playing the same simple melody. Additionally, each has an accompanying mp4 video of the frequency spectrum of the melody as viewed in the music sampler used to make the clips. First, choose the audio labeled "sine" to hear the basic melody as created using a single frequency. Open the video that corresponds to it and note the individual peaks of each note. Here, frequency is the horizontal axis (log scale), and amplitude is vertical. The melody played is, musically speaking, A - E - D - A; these notes have the following frequencies: A = 440 Hz; E = 660 HZ; D = 586.667 HZ Take a minute to orient yourself to the log frequency axis and conrm the above values make sense based on what you see and hear
