Playing with motion in still photography

These shots were all taken at relatively slow shutter speeds to impart a feeling of movement.  It works in two of them but, oddly enough, in the first, the effect is more akin to a double exposure which it is not.  My friend at the piano got caught in a chord in an exposure of several seconds.

 This shot of a streetcar in action at the corner of Queen West and Bay Street in Toronto was taken on what had to be the most miserably cold night of the year.  I went on a photo shoot with several other people and got so wrapped up in what I was doing that I didn't even notice when everyone else gave up looking for me, packed up and headed for the nearest coffee shop.
