Theory – do you need it?
Some players who’ve made a big name for themselves have never learned theory. Some players think learning theory will make them more generic and not as ‘unique.’
But, players who tend to advance faster and have better careers have often mastered theory.
You want to push beyond the first position pentatonic licks you’ve been doing for years? You want to write something that isn’t blues based or 3 chord country?
You want to learn at least a bit of theory.
