I do both, but I would say I use my ear even when reading off the charts. A lot of charts aren't really written for guitar even though there is a score, so sometimes I "judiciously" use experience (ear/anticipation) to where the chord should be going and what form needs to be played. I have been playing off charts for quite some time and my ear playing has suffered, so I have been going to various jams to get some exposure in this regard. In my old age I have even been taking music lessons for the past few years as I was weak in playing the more complex odd time rhythms. BIAB has been of immense help to me in both ear playing and chart playing. DennisD
