This is the first four lines of "You Aren't a Chef" from my last 24-hour album. The green lines are my guesses at the intended pitches.
The results aren't all that surprising... I slide between notes way too much I think (although I guess I need to see what's normal, but e.g. the section at 5 seconds), I overshoot and fall back, and I end up flat a lot. (But then I'm sharp on the last phrases... although I pretty much nailed the highest note, which is near the top of my range.)
I'm kind of surprised at the amplitude of the vibrato for the two places where I really applied any.. the one at 17 seconds starts flat but does end up centered correctly, but it swings up and down by three-quarters of a step in each direction.
