The rather brilliant Interstellar score was produced by Hans Zimmer (who else) and the first thing you should do is check out this performance on a Risa stick (sadly Santa didn’t bring me one for Christmas) before you start learning.
I got in touch with 이기석 (hopefully I’ve got that name correct) and he very kindly sent me his tabbed version. Google Translate helped us through the language barrier.
The tab is for a low g ukulele and if I’m honest I restrung my Outdoor Ukulele Tenor to low g just so I could play this song. It’s the first time since I started playing ukulele that I’ve restrung to low g.
The tab isn’t overly difficult to play. Watch for the 3/4 timing and you should be ok. Keep a steady count throughout tapping your foot to keep the rhythm.
