Joy,

I would think all you need at the moment is a transposing chart (music store item, and also they exist online). I mean really, it sounds like your ear is guiding you for the rest.

There also was a hilarious and really accurate chord-finding method described in a past thread-- I can't look it up right now-- where the basic idea was "try this chord, and if it sounds crap try another chord;" for what you are doing now, you don't need much more.

Another good Mudcat thread is one about modes. If you take a look in the permathread index (see FAQ drop-down menu in box at top of threads) you can find it. Some other good theory threads too, just look around and HAVE FUN.

Welcome to Mudcat!
