CategoryBach at my side, Goldberg Variations
Variation 28 is a two-part toccata in 3/4 time that employs a great deal of hand crossing. Trills are written out using thirty-second notes and are present in most of the bars. The piece begins with a pattern in which each hand successively picks out a melodic line while also playing trills. Following this is a section with both hands playing in contrary motion in a melodic contour marked by sixteenth notes (bars 9–12). The end of the first section features trills again, in both hands now and mirroring one another.
The second section starts and closes with the contrary motion idea seen in bars 9–12. Most of the closing bars feature trills in one or both hands.
Playing this variation properly requires loads of virtuosity. The melody at the top sounds staccato and it recalls tweeting birds, while trills are making a line that virtually divides the melody from the accompaniment at the left hand.
I’m using the repeats to alternatively show the melody and the accompaniment, which is always built on the structure of the Goldberg Variations, given by the base notes.
