I did a gig last Sunday with a UK pianist composer called Andrea Vicari (Streatham) and a Chelmsford based sax player called Zak Barrett (the geography is relevant). Myself and the drummer were local. Andrea turned up with charts for some rearranged standards and a couple of her own tunes. The standards were a mixture of dots and chord sheets but her own compositions were dots. One of them, which had an African Hi-Life vibe, was wall-to-wall dots. There was a 16-bar section which she referred to as ' the Weather Report' bit (gives you some idea of what it was like). No time to rehearse. She said we could leave it out if we wanted but Zak and I looked at each other and said 'let's do it'. Remember, the performance of this tune (and all of the others) was in front of an audience in a live situation. We hit about 90%. My point is, in no way on God's earth woudl that have been even near to possible with tab. This coming weeked, I am performing with a quartet featuring a guitarist from Oxford, a saxophonist from Brighton and a drummer from Gateshead. We are hoping to get an hours rehearsal in to 'top and tail' the charts. We will be playing a whole gig of Pat Metheny tunes (about 16 charts?). Dots and chords again. There is NO WAY this would be possible with tab.
I know people will say 'I don't need to be able to do that in my situation'. Of course, that is true. But that also means that your situation will never change. Being able to read, even at my level (I am not as 'fluent' as a top pro), is a MASSIVE boon to playing the best music possible given the variables at play (travel, geography, time etc). Tab would just not deliver that level of flexibility. To me, it's a no-brainer.
