I'm a beginner of just more than a year. I select tunes I want to learn based on how much I like a tune. My theory is that if I like it, I will be more motivated to practice and learn, plus, why learn a tune I don't like. The flaw in this theory is that some songs I like are way over my head for now. In these cases I move on and will get back to them months, years, or decades from now when my skill level allows.
It seems that every tune I fancy inevitably is in a different tuning. Now to my question. Am I doing my learning a disservice by changing tunings so frequently as a beginner?
My concerns are this: I will never 'learn' the fretboard. Intuitive noting is lost. I'm not a real musician if I don't know the notes I'm playing (I was told this last weekend).
Fret less banjos were the beginning, so I don't concern myself too much with these notions, but if I focus on learning open G tunes will it pay dividends in the long run, or am I just taking a different route that will get me to the same place in ten years? And yes, I may be overthinking this.
