In my specific case, I have a baritone ukulele which I tuned to all-fourths (personal preference), making its strings match the lower 4 strings of the standard guitar tuning (G4-D4-A3-E3). It also matches the strings of the standard bass tuning, just 2 octaves higher.
I would like to find out how to play chords on it. I know some music theory, and could definitely build all the chords I want on this tuning myself, using some laborious and exhaustive fret-searching. But I don't want to do that.
Is there a simple, theoretical method to write down chords for strings using a specific tuning? Some pen-and-paper method, based on the circle of fifths?
