In the artificial harmonic section from bar 57 (which I am slowly getting to grips with) bar 61 evidently requires the drop D to be played with the thumb but at the same tine the thumb is supposed to be playing an A flat on the 4th string. This is obviously impossible as far as I can see, so should the subsequent B flat and F still be played with the thumb, which is still tricky but definitely not impossible or is it possible to leave them all out?
When I was ten, I thought my parents knew everything. When I became twenty, I was convinced they knew nothing. Then, at thirty, I realized I was right when I was ten.
