The short answer is no, but the long answer yes. Music theory is the language of musicians. This means in any music setting, you’re always better off knowing at least the very basics. You don’t need to be the next jazz master to fit in with other musicians but understanding what major & minor are along with the basics about scales will help you massively!

Well, that depends whi ch one you would prefer to play. There is a myth that you should start on acoustic and gradually change to the electric over time, but fundamentally both types of guitar do the same thing. They are strings on wood that make sound, therefore learning on eit her is perfectly fine.

In my opinion, you can pick up the basics & make improvements while learning guitar from YouTube & other similar sites, however it isn’t comparable to the progress you could make with a one - to - one teacher. A teacher can guide you in all areas that you don’t understand, as well as prevent you from picking up bad techniques and habits; some of which can take years to reverse once learnt.

Reading music is not the most import ant thing when it comes to playing guitar, however learning to read music will give you an advantage in improvisation & will help you when jamming with other musicians that play music from a sheet. If you would like to look into doing session work, then be ing able to read music will be very helpful for you

A variety of practice materials, regularly setting limitations on practice & learning new material are the main things that I find help to get me out of a rut. Variety is the spice of life & that certainly rings true for guitar! If you find yourself struggling to progress and you feel that you’ve hit a plateau, you should try learning some simple things you know you can definitely do but that are still fairly new to you. From there, you can start to learn new things that challenge you a bit. The main thing is working something new into your musical vocabulary.
