Improvising and playing by ear has nothing to do with learning tabs or proper musical notation. Some of the greatest folks to ever play by ear or improvise don’t even know how to read music.

It’s not to say the rest of us can’t ever be a great improvisational musician, but a lot of it is pure gifted talent.

Give it time, play every day, solidify your fundamentals, keep your nails short, and get better one chord at a time.
