I've thought for a while that the concept of teaching instruments through games is a great idea, and hope this lives up to my expectations. If this piques your interest, you might want to look at the independent PC title Synthesia (<a href="http://www.synthesiagame.com/" rel="nofollow">http://www.synthesiagame.com/</a>) which is based around a similar idea for piano; despite not particularly polished it has the core concepts down and is improving all the time. I hope that one day someone sees the potential in his and throws money at the developer to give it the time and resources it deserves to turn it into a large-scale commercial project.<p>I have great hopes for these sorts of products, and think teaching instruments via games is simply the low-hanging fruit of a bigger idea. I think using technology to improve learning is a woefully unexplored area, and that learning is a sector that is ripe for some serious disruption. I don't think textbooks or lectures are an good or efficient way to learn, but we're still using those same methods that have existed since time immemorial without strong emperical evidence simply because it's the status quo. Meanwhile, technology and our knowledge of neuroscience and psychology have improved beyond all recognition, yet they are massively underutilised in terms of helping people learn. I can't help but feel that one day all these dots are going to be connected and it's going to dramatically change how we learn and educate for the better.
