For non standard tunings I use a freeware programme called "Nutchords".

Laid out like a guitar fretboard you can alter the tuning of the open strings to whatever you want and then flip through the inversions of any selected chord, or see almost every imaginable scale. Pressing one key lets you hear the chord on a guitar and another lets you hear the same inversion on a piano. It'll do printouts too.

It's useful for reverse engineering fingerings you've seen played and telling you what the chord is too.

I can also be used for tuning up to as well.

great little prog, and it's FREE!
