In this video Becky Mason teaches sweep, reverse sweep, J, sculling draw and sculling pry strokes. She does this "Canadian syle"—that is, in an on-side heeled, wide tandem canoe, angled "facing her work," and hence she ignores all cross-bow and cross-stern strokes, and off-side heels, which are staples of paddling in narrow, centrally-seated solo canoes. Regardless, you can pick up good pointers for the strokes she teaches.
She's good; I saw her do a demonstration at a freestyle symposium a couple years ago.
I learned to canoe based on her father Bill's book and video and started out with two tandem canoes, one white water and one for big lakes that I also paddled solo. I soon migrated to a solo white water and solo cruiser because I could see the advantages. But last fall I rediscovered how paddling a tandem solo can be surprisingly fun. I had our Curtis Northstar out a couple of times last October and paddling it solo worked pretty well, better than I remember paddling tandems before. I think some of that is I've taken solo freestyle classes and learning how to control a solo canoe also works for paddling a tandem solo, as Becky mentions in the video. I still find though that using cross strokes and maneuvers in a tandem canoe isn't easy, nor as elegant. At least for me.
