pitch-master gives you a perfect pitch in a few months! The application is mainly designed for children 7 and under. Even 3 year old kids can use it by themselves.
Why is it so easy to use for kids? Because, not like other absolute pitch training methods, this application does not use any musical notes.
What you have to do is just memorize 9 tritone chords and the corresponding colors.
Each of the flag colors represents a tritone chord. For example, a red flag represents a C Major chord.
The learning method is based on scholarly studies.
To be an absolute pitch possessor, you first have to listen to simple chords over and over again (ideally everyday), and memorize those sounds.
The intelligent algorithm generates appropriate questions for all user levels, not just random questions. It helps you to learn without getting tired of it.
