Do you ever get completely stuck figuring out one or more chords in a song? (I do.) ChordMatch provides a little help by listing chords that contain the melody note -- that is, chords that match any given note. You provide the name of the melody note (or any note you can identify as part of the mystery chord) and ChordMatch tells you all the common and some not-so-common chords that contain that note.
As far as I can tell, there are five general alternatives for figuring out the chords to a song from a recording. These are:
If you're hung up trying to find a chord, try to identify a single note such as the melody note by matching it on the guitar. This works best if you select a note where the melody has "landed" when a chord change takes place. Try to avoid so-called passing notes which are not a part of the underlying chord. Typically, if the melody lands or pauses for a moment on a new chord, that melody note will be in the chord itself. Of course, the best thing is to hear and match a note that the rhythm instrument is sounding as part of the chord.
Once you've identified a single note that you believe to be in the chord you need, then you simply try all the chords that contain that note and hope you can hear the match <g>. If you include all the extended and altered chords with which a note can fit, and if you don't apply judgment as to which chords to try first, then you're going to be working at it a VERY long time. ChordMatch lists common chords that match your specified note, thus giving you a set of chords to try before pulling out the truly weird ones. ChordMatch chord suggestions are grouped into more-common and less-common matches.
So find your note, get your list of chords to try, and check them one at a time. (I can't help you hear when you've got a match -- it just takes practice.) Don't stop at the first chord that sounds OK, unless you are sure it is exactly right. I've seen quite a few charts on the internet where the person figuring out the chords obviously said "close enough", but their chord selection is wrong and they've basically reharmonized the tune. Keep trying until you find the best chord match.
Good luck, and I hope ChordMatch helps you in your efforts.
