Perfect picth is misunderstood by thousands of people, and look at who they are...
ok, about associations, my favourite trick...... Play a C, and go, wow thats the first note of the rite of sping (or anyother piece) and they go, urm...hang on, what note is rite of spring, they start hearing it, and then the pause, then they start to isloate the note, and then evetually they get it. Thats not perfect at all.
Don't try to aquire perfect pitch, it's a total waste of time, you could spend that 5 minute session dictating tv themes, and seeing where you went wrong, and doing other aural skills and your pitch would get to an equal standard of someone with perfect picth.
Well congratulations you are one of them.
You have maybe never heard that our brain consists of two parts one that is consious(very small) and one that is sub-consious(maybe unlimited). To get something into the subconsious you have to do is to do it regulary. How come we can play pieces? well because of practising it has come into our subconsious. How come bad habits arise e.g because we do a bad things consitently and then we have to practice right to get rid of it. What you need to have inborn to accquire perfect pitch is the ability to recognise frequencies and that is inborn in all of us.
You also do dictation, reading, writing and all these kind of things. Absolute pitch is an optional skill to acquire but it's not essential. Relative pitch is a must.
Perfect pitch is a hinderence, you meet people like nightengale11 and feel like your smasing your head against a brick wall. People always insist upon telling you about it, and blah blah blah, it's no big deal really, but people make it one.
