Musictheory.net is a web 2.0 tool that teaches you many things about reading music and playing it. You can choose from a lesson, trainer, or a utility from the list, There are many exercises as well that would help a lot for learning music identification and ear training. This web 2.0 tool has many pros, but some of the cons are that some of the lessons cost money. I haven't ever used this web 2.0 tool, but I'm going to be using it more often now that I'm learning guitar and trumpet.
I would give this tool a 4 out of 5.
