6: Exchange places passing left shoulders with two galliard steps, left and right, and then face

Note:  This next section is an approximation to fit the above music, required because their otherwise perfect performance is marred by their not playing the entire written galliard section
12: The man does four galliard steps, improvising the pattern so that he finishes facing the woman
12: The woman does four galliard steps, improvising her pattern so that she finishes standing next to her partner, who should turn to face in her direction - ending up proper and (optionally) holding inside hands
Note:  The actual sequence of steps as indicated in the manuscript is forthcoming.

Riverenza grave with joined hands to end the dance
I would like to acknowledge the help provided to me by the article by Andrew Vorder Bruegge that appeared in volume 4 of the Letter of Dance, and which I found on the web at http://www.pbm.com/~lindahl/lod/vol4/bassa_gioiosa.html#f5.
While I translated the facsimilie source myself, it took looking at Andrew's reconstruction to reconcile the one nagging issue that I couldn't fix (too many beats in part 3), not to mention numerous other minor issues, 
and without it I may well have never finished my reconstruction.
Anyone comparing the reconstructions will certainly see how close they are, but also the minor differences, usually with positioning or feet.
The one, perhaps major, difference is in the beginning of the last repeat of the music, halfway through part 5, where I have the couple face each other instead of remaining facing forward.  
The manuscript seems clear about how the trabs are flanking forward and back, and there is mention of turning the flank just after the ordinarii going forward.  I feel that the resulting approach and retreat might add something to the dance,
but if this has resulted from a complete mistranslation (it's happened before), then I'll happily re-reconstruct it and make any necessary (and/or suggested) changes.
