@randulo it sounds like you have what is usually referred to as 'perfect pitch' so you see an 'A' and expect to hear an 'A' not a C etc.
No, no, far from it. I worked with a classically-trained blues violinist, Don 'Sugarcane' Harris, who did have it. We'd hear a car horn and he say, "D7th!". But what I meant was, I
think in concert, always have, and the little I could read was in concert. Handy, by the way, if you're looking at Schillinger's Thesaurus of Musical Scales and Patterns, since the entire book is in concert C. I was just plaing to a Bob Mintzer track in C minor (Do mineur if I had to yell it out at a French jam session) and I'm playing Am on the alto, but I never think of A except if I'm reading or asked to play an A on the saxophone.
I often can hear the notes of the guitar strings, though, if I try to picture an E before I hit a string. That's just some kind of habit.
I did think, when I began on the saxophone, especially with Internet lessons, how it made sense to have all sax keys names the same on the whole range of saxes. I think you are right about that, at least it makes total sense for that reason.
