Minuet in G (Beethoven)
Like the A section, the B section (or the Trio) is composed of two 8 bar passages for a total of 16 bars. Like the A section, it begins in the tonic key of G major, and modulates to the dominant key of D major at the end of the first 8 bars. This passage is repeated. The second 8 bars begin in the dominant key and end in the tonic key. These 8 bars are repeated. The entire B section is characterized by flowing, uninterrupted eighth notes in the right hand.  The left hand plays quarter notes but briefly joins the right hand in playing eighth notes at the beginning of the second 8 bar passage.  The left hand returns to playing quarter notes as the passage closes. When the B section is completed and all the repeats have been taken, the piece returns the A section. This return is usually played without performing the repeats.
