What's the hardest chord you ever encountered? (Page 6 of 6)

Or play some of the notes way up near the 12th fret.  It might sound funny, but it'd be open.

I personally find B difficult if played the orthodox way, because my hands are proportionate to my 6'4" - 250 lb frame. They're not like Chris Squire's or anything (bassist for "Yes") but cramming 3 fingers next to each other on the fret board is only possible on my classical (2" wide @ the nut). As a number have suggested, reconfiguring ones fingers is sometimes the only solution. For A and B, I now invert the knuckle of the middle finger to cover the D and G strings, and then put the ring finger on the B to complete the shape.

The opening instrumental section of "Blood on the Rooftops" (Genesis) also contains a couple of odd / difficult ones which aren't any charts I've seen. A combination of practice and experimenting with which fingers to use will eventually solve any of them.

The chorus for the Genesis tune "Ripples" contains a Gmaj7 which I can't get to smoothly from either the A or E before it. Blasted little finger responds slowly to that reach across the neck to the 4th string ... more practice!

I agree with Guitaardophil about Paul Simon's "50 Ways" ... tricky combos.

i feel stupid saying this to guitarists but some chords are like a brother from another mother, they look similar and quite often sound similar too. for example, if guitarist 1 plays G , and guitarist 2 plays Bm you get the effect of Gmajor 7. it may not be technically Gmj7 but it's close enough for the layman not to notice the difference. another one is G and Em = G6. you can go up and down the fingerboard like this, spend some time working them out.
