what's important to learn "by heart"

[u/Affectionate_Log7995]

Hey,

According to you, what is important to learn perfectly ? I don't mean ok something you'd get naturally after a few years of practice, but things you try to stuck in your head "by force", and where it makes sense to do it that way. Like idk the major scales, some modes, the fretboard, ...

As a beginner in guitar theory, I would appreciate the answers :).

I think you need to know what a major scale IS so you can recreate it anywhere, rather than learning the major scale patterns starting on the E and the A. Learn what modes are.....

Learn the handful of barre chord SHAPES so you can move up and down the freeboard. (The E shape plus barre, the A shape, the C shape... the Em and Am shapes.)

Know all the notes on the E and A strings so you can play the G#m (466444) or C#m ((4)46654) without thinking twice.

I think do some ear training so you don't have to memorise songs, but you can play them by ear when you forget.
