Just ran across this YouTube video of yours from a few years ago.
I wasn’t sure where to post this so I created a new Topic.
I remember watching this video when it was posted and thought, “This will be incredibly helpful.” 
But I failed miserably at hearing whether the notes were going up, down or staying the same. I couldn’t find my way through Twinkle, Twinkle, Little Star. But after much work learning how to listen carefully, practicing scales, learning the fretboard and picking out melodies on my own, it has become easier to learn to find a familiar tune on the 'ukulele. 
Practice, Patience and Persistence, are a huge part of my 'ukulele success.
Mahalo to you Brad
