With much due respect, I should not have said say I needed tab for any reason. I simply prefer it.Why do you need tab for fret position? Traditionally guitar notation has position/strings/fingering without tab. The notion that you can notate stuff in tabe you can't do in regular notation never made sense.
To your point, I will admit that Tab is a poor presentation of tempo. but I read both languages. I prefer Tab because I am more familiar with it and I've adapted it to my particular style. I read well enough to learn a lot of pieces for which staff is the only source. After I voice such a piece, I register it on tab so that my more familiar language is available. The transcription is quite valuable as an exercise, yes? I think so.
Great points ^ and yes, improv to new and exciting parts of the neck is constrained by tab. Once I know (and/or recall) the piece, imrov flows kind of easily. When I find a lick worth writing, I write it down and get back to wandering and wondering.
On closing, nice to meet you new friends. I trust I do not offend? I certainly do not intend...
