Hello fellow guitar players!

I was looking for some general advice now that I am appraoching the 6-month mark of starting guitar.

About a month ago (or maybe a little longer than that) I finished the guitar fundamentals 1 course and was about to move on to guitar fundamentals 2, but decided I thought I would try my hand at some songs I was interested in learning and within my means of guitar playing. (All For You- Sister Hazel; Let it be; Jumper- Third Eye Blind; Starting Over-Chris Stapelton as a few examples for songs I have learned to be able to play decently and with little error and taught me some cool strumming patterns and chord variations)

Through doing this I have started to hone my skills of some of the chords/chord changes that are taught in fundamentals 1 (I do not want to move on to fundamentals 2 without having pretty well mastered what was taught in fundamentals 1).

I'm now at a crossroads where I'm realizing even if I can play (with a few buzzes here and there) some songs I am not able to sing along.

Is singing along to the song while I am playing being too unrealistic for my tenure? Should I push along to Fundamentals 2 now that the songs in Fundametals 1 have been pretty well mastered at this point? (Again, a few buzzes here-and-there but I can play each song decently well).

Thanks for advance on reading the novel :) just looking to make sure I don't move forward too fast or skip crucial steps in learing the guitar!

Austin
