This version of "I'll Fly Away" is intended to help beginners start learning by ear. The tab is available, but I strongly recommend you spend some quality time with the video before using the tab. Learning by ear is the best way to learn banjo, and tab can be used in a way that isn't detrimental to your playing. And I don't care what anyone says - you can learn by ear.
For example, challenge yourself to learn all of the melody notes by ear in "I'll Fly Away," and then use the tab for the 16th note phrases. Or learn every other measure by ear.
Obviously this takes some will-power because the tab is there in front of you, but you can put post-its over half of the measures, or simply scratch them out with a pen.
Stick with it and please let me know if you have any questions!
