Hi martinovation,

I'm a bit like you in that I learned how to read music for a good year but eventually, it just slipped. It's always useful to learn music especially if you want to learn a song that isn't necessarily in tabs. Learning actual sheet music and learning how to read it is invaluable for learning many more songs than one could ever learn from just tabs. Someone who could read music can possibly take a song that's played on another instrument and transcribe it. I find that really interesting.

For a refresher on reading music, this lesson is always a great starting off point: https://www.guitartricks.com/lesson.php?input=24850&s_id=2051
