This app is for everyone who plays a musical instrument, everyone who is interested in composing their own music, and everyone who is preparing for music theory exams.

To help you learn music theory well, this app has video lessons that approach each concept in a unique way to help you understand it thoroughly. It also provides hundreds of practice problems that you have never seen before, including lots of ear training, which is the part of music theory that requires the most practice. This app has three sections: learn, practice, test.

A one-time in-app purchase is required to gain lifetime full access to the entire app including future updates. All learn sections and the practice section of the first lesson in each chapter are free.

Learn: Watch a short video explaining a topic, such as enharmonic equivalents or ties and dots.

Practice: Do problems related to what you've learned in the learn section and get immediate feedback on your answer. In order ensure thorough understanding, you will need to answer each question correctly twice. If you answer a question incorrectly, it will be asked until you answer it correctly three times. The progress bar at the top shows how many questions you have left (increases when you answer incorrectly, decreases when you answer correctly)

Test: Check your understanding on each chapter with 5 questions selected randomly from each lesson. Each question is asked once regardless of your answer. This app gives you feedback on your overall accuracy, accuracy for each lesson, time, and acceptable, good, and excellent times.

Content: This course covers everything from reading notes (basic) to harmonization (advanced). There will also be both basic ear training (simple pitch patterns) and advanced ear training (questions based on a symphony). It will cover all topics on the AP and ABRSM music theory exams.
