Though the sonata is marked as being in A major, Beethoven does not write any satisfying cadences on the tonic key; the exposition and development do not include a single root position A major chord. The first tonic chord in root position appears towards the end of the recapitulation. It appears once more at the end of the recapitulation, but even then (4:35) is blunted by the omission of the fifth scale degree.
