Glenn Gould plays Mozart - Piano Sonata No:12 in F. K 332 - 2. Adagio B flat major.

“They were once believed to have been written in the late 1770s in Paris, but it is now thought more likely that they date from 1783. Vienna has been suggested as a possible place of composition, with others believing the sonatas were written during a visit to Salzburg where Mozart introduced his wife, Constanze, to his father, Leopold. All three sonatas were published in Vienna in 1784.”
