I'm looking for a chord builder web site. Is there one that shows what strings are being played and what chord it is? I'm specifically looking for the following chord, but ask for a web site so I can learn to fish.
This site is gona do it for You:
Here You can browse by chord type and see chord shape on fretboard, or enter the fret numebers or x - and find a chord name.
This is a basic to intermediate chord site, You won't find any advanced voicings there.
Chorderator lets you look up chord shapes by name, names by shape, and scales, in any tuning.
I use this one:
Don't let the url fool you, this little tool can give you chords and scales for most stringed instrument.
Very handy. :-)
The iPhone app Guitar Toolkit is awesome for this type of chord search. You can plot the exact fingering and it will tell you what chord you have. This differs from most chord lookup sites and apps in that you don't have to search through a bunch of chords to identify the one you are looking for.
There may be some other resources out there to look up chords in this "reverse engineering" approach, but this app is something I started using when it first came out and is a good all in one tool for a number of things.
This is a good one I've been using though: http://musictheorysite.com/namethatchord
