Hey Ceej,
If your having trouble hearing the pitches, the biggest reason is that your still trying a little too hard. Or you are still looking for something that is not there, and your just overlooking it. The Pitch sound is there, just relax and listen effortlessly. See when your trying even a little more than you should, you are not letting your ear open up. It’s saying back to you, “you are pushing me too hard, kiss my arse. I’m not going to let you hear anything.” And you start to get frustrated, and you try harder and harder, and you begin to draw a blank. This is a very common error, and this is what gets people to believe that perfect pitch isn’t for them. Cause they try so hard to get it, and they go about it thinking it is intellectual. If this is the problem, just let it come to you naturally. Don’t force, If you feel as if you are even trying to hear it. Stop for a second and relax and try again. Also, re-read the post I put up about the D and the Eb.

Now if you are having trouble with recognizing the pitches and discriminating between them. First make sure that you are hearing all 12 pitches correctly. Then once you know all 12, learn to sing them. This will help to learn these, and get them implanted in your mind. Do this even if you’re not a singer. Note: say your playing guitar and your singing with the notes, you don’t have to be perfectly in tune. This is extremely hard to do if you’re not a singer. So don’t worry about being perfectly in tune, just get as close as you can. BUT make sure your not too far off, like your trying to sing a C, and you’re singing a B. Just get as close as you can. This will help fix this.

Now if this wasn’t what you were asking, be a little more specific with what you’re having trouble with and I will re-answer your question. Or if it is what you were asking and you are still having trouble. Email me at Mikelbwv@aol.com and I will try my best to help you though it. I hope I helped you with this. Take it easy.
