Yes, the staffed notation. The scary little lines and dots on that graph. It's hard in the beginning, but in the long term, it's the best solution to learning a lot of styles of music.
The harmonic patterns, syncopated beats and the melodies are much simpler when you know them as notes on the clef and NOT synthesia files or guitar tablature. Guitar tablature is fantastic for beginners but not a useful tool to learn the musicality behind why a lot of things work why they work.
To learn musical notation quickly, tons of sight reading exercises are available on YouTube. You can play your instrument along with it and in a few months be good at sight reading the different chords and melody shifts being used.
Plus reading notation is necessary because, for hundreds of years, it has been the official language of music. You can move the piece to any other instrument, even software quickly. The music theory is devised to help people remember and play music much more comfortable.
So save time and learn musical notation as fast as you can. There are tons of resources to teach that all over the internet. Of course, tutors can save a lot of your time while learning this. Overall, it's a must in your musical journey if you want to make it in the pro circuit.
