Absolute－Develop Perfect Pitch

Absolute is an app that helps you to develop Perfect Pitch - the ability that allows you to identify and recall musical pitches quickly and accurately.

WHO CAN USE IT?

The widely accepted position is that Perfect Pitch can be developed only by kids within the so-called critical period of learning.
However there are some studies that show that some adults also could acquire this ability with appropriate and consistent training.
So it is not guaranteed that you acquire a genuine Perfect Pitch, but there are very good chances that with sufficient practice you will develop a good tonal sense and the ability to identify and recall pitches without any reference pitch.

HOW IT WORKS?

The app provides a well structured plan of exercises.
The plan consists of 22 levels. Levels differ from each other by the set of pitches(notes) they include.
Number of pitches in a level gradually increases as you progress through the plan.

There are 4 types of exercises in a level:

1. For each note, you learn tonal mnemonics, called resolutions.
A resolution is a short melodic phrase which always leads from the original note to the root note (note C).
Resolutions allow you to form a unique mental picture for each of the 12 notes.
The app plays you the resolution and visually indicates which notes are being played. You play the same sequence of notes in response.

2. You develop the ability to identify the resolutions by ear.
The app plays you a resolution but doesn't show you which notes are being played. You try to identify the resolution and play it back.

3. You build up the association between a pitch and it's resolution.
The app plays you a single pitch. You try to recall and play the resolution.

4. After you have sufficiently practiced the previous exercises you are given the task to identify pitches.
The app plays you a pitch or a series of pitches and you play the same pitch(pitches) in response.

There are two properties of your performance that allow you to advance through the plan: Accuracy and Tempo.

Accuracy is the percentage of the correct answers in a given exercise session. You need to gain at least 90% to pass an exercise session.
You also need to complete an exercise at a specific tempo (passing tempo) to unlock the next exercise.

The key idea behind the increasing tempos of the practice sessions is that the shrinking time constraints force your brain to internalize the mental processes involved in the pitch identification activity. In other words, the brain moves the processing from the conscious to the unconscious realm. And as the result, at some point, the process of pitch identification is optimized to a level where you don’t need to use the resolution mnemonic any more. You just hear and immediately recognize a unique image of a musical pitch.

A NOTE FROM THE DEVELOPER:
I am a musician myself. I play and teach fingerstyle guitar. I don’t have perfect pitch. So partially, I developed the app for myself and my kids. I made a lot of resea
