What is a good topic to teach a group of beginner guitar players?

First of all I think you should teach them how read tabs, string tunings, tune their guitar, and the names of the different parts! As well as the scales! If you are done with the scales, then, tell them to practice reading the guitar tabs, guitar chords which can help them further.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
