Chord progression in CGDA

 While playing around with the mandolele (baritone uke tuned CGDA) I found some chords and had came up with something involving a progression from B7 to Am, which sounded lush on the instrument. I tried those chords on gcea Ukulele, not nearly as good sounding, too bright, but the mandolele has a lovely dark tone. 

It also sounded nice on piano...

Mandola tuning on my baritone uke

 Following information provided by members of the mandolin cafe forum, I took the 5th 4th 2nd and 1st strings off my classical and strung up the baritone uke to CGDA-mandola tuning!

Ideally it wants new strings, they've been on the classical since 2015 but not played much. The 2nd string (D) sounds a bit dead. But its still very playable!
