Rock critic J.D. Considine had some interesting comments about President Bush's infamous guitar phot op (taken with a guitar that Nashville hat Mark Wills gave him as New Orleans was sinking.)
"What bugs me about the photo, however, is that it gets described as showing the president “playing guitar,” when at best he’s only posing, trying to look like he’s a-pickin’. How do I know? Just look at his left hand. Like many a duff guitarist, he’s formed the hand shape for an open-G chord — except that instead of having his fingers in place to play G (third fret on the lower E string) and B (second fret on the A string), he’s a fret off, at G-sharp and C. His little finger may be adding an A (fifth fret on the upper E string), but it’s hard to be certain. In any case, were he actually to strum that guitar, the result would be utter dischord, revealing him as someone who doesn’t know diddley about guitar. Instead, he poses quietly, and only instrument geeks like me notice."
