Yes I have arppegiated almost all the chords in the first couplet. To emphasize the beat accurately, usually the chords in the strong beat should be arppegiated, whereas the chords in the weak beat should be played in time. This is 3/2 time, so only the first half note is strong beat. This way of playing is shown perfectly in Michele Benuzzi's recording(search KZfaq for his rendition of this sarabande). However I wanted to emphasize the lute or harp like sonorities, so I chose to arpeggiate most block chords, but for the variations I mostly refrained from arpeggiating the notes in the weak beat so as not to disrupt the beats.
