I want to know if by learning a song from a tab I'll somehow get better at learning a different song.
I have this feeling that by learning a song from a tab I'll only succeed at learning that one song. This inkling has caused me to avoid learning any tabs up to this point and just focus on chords, learning the names of the notes for the frets, and try learning scales so I can sight-read sheet music.
I can read sheet music but obviously it's not as simple as just being able to read it when it comes to the guitar. All the same, sight-reading sheet music is a transferable skill, whereas I'm not sure about reading a tab. Will I be starting over for each tablature?
Maybe what I'm asking is: Is it possible to sight-read tabs?
Just as clarification, after posting this question I realized my main concern was not knowing how to lay out my left hand fingers when playing tabs, as they usually don't indicate finger position. This concerned me because I felt that by not having a method for knowing which fingers to use learning a tab would not be transferable to another tab because I would pretty randomly choose which fingers to use on the next tab and so the order would be different, etc. After realizing the crux of my concern, I found this post which has allayed my fears remarkably.
Thanks for all the answers, and sorry for not being clear!
