It’s nice to have a Chord Chart handy. You can find them online, most are on pages that will bury you in ads, site banners and pop-ups. Many are just click bait.
Here’s a good one, from Luna Guitars . It’s clear, concise and Printable! Simple, easy to read, beautiful.
Thanks to Luna Guitars and while you’re at it, you may enjoy checking out their wares. Some excellent instruments (not just ukes).
