I've just started work on my solo for the first time this month.. I have a callous on the index finger on my picking hand from doing so much finger tapping, and I've come up with my own sort of appregio thing. I'm really happy with my progress because I am starting to break out of my Pentatonic Minor cage. On that note, no pun intended, I have to say that my submission this month may not sound as great as I would have liked but I am pushing the envelope so it's ok.. though I still have a week or so left to work on it, which may allow me to get it exactly how I can hear it in my head. I've also been studying a lot of theory over the last few weeks, and I can see it is starting to yield some fruit in the form of the appregio and moving up and down the neck to compliment or counterpoint the bass line.
