This is related to Littletune's "Hearing the Intervals', but I think different enough to be its own topic.
I never had any ear training, period. When I started lessons this year after my 40+ year vacation the teacher tried asking me to identify intervals, and we established very quickly a) that the only ones I really knew were unison and octave and b) there was a real danger I would burst into tears. So we agreed to leave intervals alone for a while. Then Littletune's thread came along and the suggestions on it have been FANTASTICALLY helpful, especially the ones about relating the interval to a well-known song (which, believe it or not, I hadn't head or thought about before).
So, thanks to everyone here, I can now actually practice intervals without suffering mental trauma. The next question: what are some reasonable goals I can aim for? If I jump into doing all 24 at once it will be hopeless. Do I start by learning to recognize one interval, like thirds, then move on to others? What are the most important ones? And, how accurate is a normal person likely to get in this?
Thanks for your advice, --s.
