More cool stuff found on YouTube. Ok, not to make this blog an aggregate reader of YouTube, but I wonder how my instrument learning days might have been different had this been available. It's worth watching the whole thing to see this technology. By the looks of it, it appears to be limited to instruments that can play only one note at a time since it seems to be designed to interpret pitch and rhythmic accuracy of a single note.
I'm fortunate to get to play with a great group of players every week, but for some folks, even experienced players, this looks like a great way to keep your ensemble chops up!
