Perfect Pitch Trainer

Training program for developing Perfect Pitch.
This is designed to assist the skill of listening to the particular quality of a note to determine its pitch from the sound alone.
The user is played a note from a 4-octave range, and must try to identify it by listening to its audio quality, or color. For example, F# has an edgier sound than Eb. Each note can be placed in a spectrum similar to a color wheel, repeating each octave. Over time, you can learn to distinguish these. It is like a vowel sound, but very subtle.
This is how people with perfect pitch can tell the name of a note just by hearing it once.
Filters for the range include choice of octave(s), whether to use a diminished chord, and the root of the chord.
A choice of 2 instruments is given.
There are training modes to help, including showing note name, associated position on a color wheel, last note played, and last 8 notes played. There is a help screen.
Scores are not kept, since this a development tool and should be used in a stress-free way. Just keep listening, start with the C diminished chord in one octave until you can hear the difference between the notes, and place them on the color wheel. Then move on to more octaves, and other diminished chords. Dont try to relate the notes to each other - thats relative pitch. Take your time, it can take weeks!
