I wrote this a while back and thought you guys might be interested in the ideas presented. Guitarists in particular (as opposed to other instrumentalists) amaze me as they generally have a LOT of trouble playing simple melodies by ear without mistakes. Years of relying on tabs and pentatonic scales will do this. If you can't play your national anthem or simple tunes like happy birthday or twinkle twinkle by ear in any position and get it right every time, this method will help you. http://www.jsguitarforum.com/forum/showthread.php?t=56336 I will be re-writing this soon, and I'll update the thread when it's done. I plan on inlcluding how to sight read standard notation using solfege as a foundation, and hear the melody in your head before you play it. Also, transcribing directly to standard notation will be covered. I'd also recommend Bruce Arnold's book - "Fanatic's Guide to Sight Singing and Ear Training", it contains proven solfege exercises that will develop your sense of functional pitch. To those that have used interval recognition when learning ear training, I highly suggest augmenting your knowledge with functional pitch recognition. If anyone has any queries, post them here and I'll try to help.
