"The Goldberg Variations" Aria - J.S. Bach

Here we go... The piece begins with an expository A section. It is a parallel period followed by a phrase. The first phrase of the period ends with a half cadence and the second ends with a perfect authentic cadence. The phrase after the period is transitional; it ends witha PAC in the key of the dominant. Therefore, the A section is open. The A section is then repeated. The B section is two phrases, the first ending on a PAC in E and the second ending on a PAC in G. It is another expository section and does not develop anything from the A section. Because no material from the A section is visited again, the B section is simple. This piece is in open simple binary form. And it's played on a harpsichord. =)
