What is Functional Ear Trainer?

Functional Ear Trainer is a relative ear simulator that will be equally useful for beginners and experienced virtuosos. The program is based on the method of Alain Benbassat, based on the recognition of tones. Practice every day for ten minutes, and after a couple of months the result will pleasantly surprise not only you, but also those around you.

You do not have to learn notes separately, you are invited to immediately go on a journey, in the final of which you will learn to understand the language of music. In the theoretical part, the user gets acquainted with such terms as notes, intervals, mode, key, and so on. Basic training includes dozens of lessons, at the end of each lesson, the student is waiting for testing. If the test is successful, the program will kindly offer to move to a more difficult level.

Features:

  • lessons of increasing complexity to improve musical ear;
  • theory, smoothly turning into practical exercises;
  • concisely designed interface.

So, step by step, lesson by lesson, you will learn to understand the musical language, it will cease to be for you a dense forest through which you previously wandered at random. And don’t let the primitive Functional Ear Trainer application interface confuse you, because the essence is important, not the packaging wrapper.
