What's up man. Here are a few chords you could use.
LH/RH
When passing to from the Gb to the B you can play GbBbE/GBbEb. On the Db, you can playDbFB/DGBDb or Db/FB/EGBbDb These are just a couple of variations that you can play. If I new how to post a midi file, I would be able to better explain how you flow into these chords. If you know I can post a midi file, let me know. God bless.
