No this isn't the start of some flaming discussion about the relative merits of TAB. It's just that TAB is generally looked down upon by most of the music world as a very poor substitution for reading actual notation. I agree. But I have discovered a use for TAB that has really helped me. I learned how to read music in junior high school when I began playing the BBb tuba. This instrument is voiced an octave below the EBG and as such the notation is written mostly below the staff. I wired my brain in the ensuing 6 years of playing to those notes (sometimes 4 lines below the staff) and, as such, have some problems reading notes that are above the staff. I also didn't have but one year of reading with the EBG (in jazz ensemble) and even then had to use brass arrangements for the bass. What has helped me is the simultaneous use of traditional/TAB lines to help get the notes in my head. On a brass instrument there are rarely alternate fingerings for the same note in the same octave. Unlike BG that has at least 2 notes (sometimes 3) in the same octave. It also helps me with learning how the hand positioning should be for a particular excercise. I have a couple of books that use both TAB and regular notation for the instruction. I also have one of the direct transcription books that shows actual bass lines as they were recorded. That has been a help in learning just how some of these famous musicians accomplished their sound.
