I just went to the 2012 Teacher Convention and was fortunate enough to go to a session by Tim Brehaut called “Technology in Rehearsal”. It was for middle/high school band teachers, but the relevance was wonderful! I learned about several iPod/iPad apps for practising/studying music, as well as several websites. Check out the iPod/iPad apps here, and the web resources here. Sight reading, ear training, rhythm (practise or put in a rhythm to hear it). They are great!
