A chord consists of notes that sound good together. The C major chord, starting at middle C, has the following frequencies: C - 262 Hz E - 330 Hz G - 392 Hz Determine the ratio of the frequency of E to C. Express the answer in a simple integer ratio. (Due to rounding the ratio will be approximate.) How many E waves will fit in the length of four C waves? a. 2 b. 3 c. 4 d. 5
