Let's end the week with a little music (part 1). Besides being an excellent communication and entertainment device, the iPhone is also an ideal teaching tool. One of our favorite learning apps is Mozart ($9.99, available here), which teaches note reading in a few minutes a day.

Mozart makes learning notes into a game, where the notes scroll across the screen and you have to identify them before they reach the left edge. There are plenty of customization options, letting you choose the clef, major or minor key, and instrument (it works for vocalists and violin or guitar players, too).

After only a little time playing, we noticed our ability to read notes getting stronger. This is a perfect teaching tool for anyone who plays music and needs to brush up on the basics.
