Burge offers two courses, relative pitch and perfect pitch. You can purchase them separately or together, I paid $200 for both. This post reviews the perfect pitch course, my review of the relative pitch course is here: http://www.thegearpage.net/board/showthread.php?s=&threadid=46236 The perfect pitch course is geared for anyone who wants to learn to identify by hearing and sing any named pitch without referring to an instrument. You will also be able to identify chords, notes within chords and keys of pieces more readily without referring to anything but your head. Burge is very logical, excellent at explaining things and the course is laid-out to maximize your learning. The Perfect Pitch Supercourse has 8 CD's plus there are 2 bonus cd's for a total of 10. You do not have to be able to read standard musical notation to take the course. There is a 40 day money back guarantee. I think he tells you that you should notice a difference within a shorter time frame if you follow his instructions. The course is largely a lot of lectures at the end of which he gives you exercises. You are not to spend more than 15 minutes a day on the exercises. He provides two methodologies for learning perfect pitch: 1) with a partner - he says you will gain results faster this way 2) by yourself - may take longer but it will work. Note: his earlier version of this course did not have much in the way of option #2 - beware if you are buying it used, you may need a partner. He explains what perfect pitch is, why it is useful, dispels many myths concerning the skill, and the various levels of perfect pitch. For example, level one is the ability to identify pitches on your native instrument, level 2 is the ability to identify pitchs on any instrument, level 3 is the ability to sing any pitch off your head. He explains what to listen for and exercises for training your ear. Every time I asked a musician including teachers how they hear an interval or if they have perfect pitch how they hear the tones, the answer was always the same, "I don't know, I just hear it". That is why some instructors do not know how to teach ear training. Most say that you have to be born with perfect pitch and dismiss you if you don't possess it. David Burge had an interesting experience. He began to teach himself Perfect Pitch when he suddenly realized that he already had it, he just didn't know what to listen for. Unlike my professors, Burge went through the transition conciously and was able to teach a friend what to listen for and she figured it out as well. You can read his account here: http://www.perfectpitch.com/chapter1.htm This is why he is able to teach it to others. He insists anyone can learn it. He has plenty of testimony and cites research done at universities at his website. His explanations at the site are better than what I am posting here. I was able to comprehend and hear what color hearing is right off the bat. I did not have a partner and followed his instructions rigorously. The color hearing seemed to come and go. Suddenly one night, I was able to hear all the pitches on the guitar as clear as recognizing the difference between peoples voices. I got 100% of them right for 15 minutes of drilling and it was so clear to me that I couldn't believe I couldn't hear it before. Alas, the next night I couldn't hear them as well. Burge says that this is to be expected however, I screwed up and stopped doing the exercises soon after. I still can play the open notes of my guitar and tune them close to pitch without a reference most of the time. I can hear that a note is flat or sharp. I am close to level 1 of pitch color awareness and have a way to go before attaining the highest level. I am planning to get back into the exercises. I can say without a shadow of a doubt my color hearing has grown, how far it will grow remains to be seen. Each person is different and the time it takes for results will vary. My complaint is that I think he should tell you up front about the partner thing. You don't need one, but it would be nice to know. You need to do the exercises on your main instrument which could be a problem for some folks. Burge says perfect pitch is the difference between watching black & white TV and color TV. When I told musician friends that I was taking this course, they were uninterested and asked me "why?". I played in a group with a blind keyboardist who could hear any note or chord or song once and play it instantly. That's where I want to be. Striving for musical excellence should never stop. Any questions or comments feel free to e-mail me or post. BTW - I am not affiliated with Burge in any way, these posts are my unbiased opinion and experience. NOTE: - It's years later, I basically gave up on it, however I'm still pretty good at getting close to pitch when tuning the gtr.
