Longest you spent learning a piece?
I've been working on some tough-for-me tunes recently. Some of them I've been working on for 15 to 30 minutes a day for more than 2 months and it made me wonder if I'm just really slow or if I'm in good company. So, what's the most amount of time you've spent on really learning a tune? By learning, I mean, memorizing it, playing the melody brilliantly, soloing competently, internalizing the changes. When you're done, you KNOW the tune, inside and outside, slow, fast, different keys, etc.
