Learnability, heuristic evaluation: In our earlier computer prototype, users had a difficult time interpreting multiple notes delivered by the interface while ear training. We discovered that learnability is best achieved by playing a single note at a time, and allowing users to guess them in succession. This design can also be smoothly expanded in many simple ways, for example, to allow for chords, or timed play.

We went from a plain white, gray, black color scheme to a wood based color scheme that uses black and a few pastel colors to draw attention to immediately relevant features. One of our user testers expressed that pianos don’t actually change color when touched and our TA pointed out that some of the colors we used earlier are very saturated, so we changed our piano's response on click be a much more modest color changes.

We will add scores according to the accuracy of the user on the test, and give them labels such as “bronze”, “silver”, and “gold” according to their performance in each difficulty level.
REFLECTION:
We learnt a bunch of things over the course of the semester, for example
