This app tests your ability to recognize all the different key signatures in music. Musical notation becomes easier to read if you have a solid grasp of key signatures. Good key signature recognition will improve your sight-reading ability and will give you a sound base on which to understand music theory and music composition better.

To help train, you can choose from a variety of different quizzes. For each quiz you are given a limited amount of time to guess each key signature. If you wish you can focus on just major/minor signatures or on sharps/flats.

You get a rating to show how good you are at each quiz based on your score results. There are charts to show your quiz score history, as well as your scores for each question in the quiz.

If you want to just target your weak areas, you can select the “Custom” quiz and just pick the key signatures with the lowest 5 scores to practice.

The goal is to get 100% on each quiz and a 5 star gold rating!!
