Uhm., ok my personal experience. I cant hear all, all. But most. Like dunno, i dont have an mp3 player , i go just concetrated down the street and i hear what i want when i want , almost. Its a learnt ability cause i realized the things i dont get to hear are the things i didn work. I played by ear during many years the piano. But.. i used most of times major and minor chords, now im tryin to work with tensions , cause its what i didnt work and its what i cant hear very well. Improgressiong though, other thing i canthear very wel its if there is a lot of movement in the work, like, .. a very worked counterpoint with more than 2 instruments. Cause, .. i cant read music so.. im nto used to have such a big notion of rythm.But i think i get in whatever i hear the 80% of the instruments and movement of any piece. There are factors, the easiests are the chorus for me, the brass after, well percussion to, ( up to the rythm), and wind is hard, the hardest for me is strings, its hard to get a uhm proper sound vibrating like a voice. Ok.. how did i get this? i think everybody can. U need to develop a litle ur ear for getting the texture, and the harmony structure. work playying songs by ear on piano etc. And dont use the mp3. Hear something, and after retain it, concetrate and work on that idea in ur head , shape it ( its not exactly memory.. u kind of rebuild it) and the high notes are easier than the low ones. I began with frankestein soundtrack of patrick doyle. untill i heard the good bass surroinding my ears like a stereo. Work on the quality , untill u enjoy the mental sound. Ul lkeep loving it and feeling somethign magical that u got by ur work . And eventualy u wont need an mp3 player , and ul work it for enjoying and it will improve more and more. And dont leave it a lot. i did when i was studyign for my exams, and.. i felt the effect , now i cant audiate that good like some monteh s ago but , it takes some days to get bakc to the level i had. Good luck.. i love to audiate.
