My sister, who is a professional violinist (as well as a teacher) was thrilled when she first used My Note Games a couple of months ago.
However, on testing with less experienced users, I have found quite a few problems. Basically, it seems that it takes years to learn to play the violin in tune. Form that point of view, it is a very difficult instrument to master and our note recognition software isn’t sophisticated enough to know when an out-of-tune note is a good effort as opposed to just plain wrong.
We don’t like to discourage kids unfairly, so for that reason we have kept the stringed orchestral instruments in Play That Note but are not supporting them in Play-A-Day.
