I hope this isn't viewed as question looking for an opinion, but more of picking the brain of people that have gone through this. I feel, and I can be completely wrong, that trying to transcribe songs (Soulshine, by the Allman Bros) is the natural way to do ear training. But here is my predicament. One day I can do really well and get a few notes and another day I can't even match the notes. Is this common? I get discouraged because it seems like I regress.
In other words my ear/brain connection is "OK" (I'm just learning) and the next day its as if I have no clue what I am doing.
FYI, I am 56 years old.
Is this common ?
