In Scarlatti Sonata in D minor K. 141 the piece starts off with a sus4 chord and then voice leads to an A major triad. Normally a suspended 4th resolves to the third of a tonic chord (in this case the suspended 4th, G, should step down and resolve to the third which is F, a chord tone of the i chord) but in here the voices of the Dsus4 chord literally leap to an A major chord which puzzles me. I have no idea on how to analyze this. Could someone please elaborate? Thanks.
