Caution advised -- from an experienced choral singer

While this is a wonderful tool for practicing ear training, it is problematic in that it encourages you to sing at the extremes of your range without offering any tips on how to do so without hurting your voice. Inexperienced singers are likely to want to push through the exercises to earn points without paying attention to proper vocal technique. Also, the pace of the exercises often does not allow sufficient time to breathe between sets -- I realize it is possible to pause the exercise, but it would be nice to have a bit of extra time built in. In sum: use with caution!
