I'm using Carol Kaye's music reading course w/manual - about $30 with shipping. I like it.
She starts you with counting the beats, i.e. is the note a down beat or one of the "e an a" notes. That really points out which are the "important" notes and how all those rests, slurs, etc are going to fit into the picture.
When you get a feel for the rhythm - meter - then you take that to your bass and find where the notes are located.
I believe playing from standard notation is a three stage process.
- Looking at the sheet music, which are the important notes and which are the "e an a" notes.
- What is the name of that fly speck.
- Where is it on my instrument.
So there is some homework to do before you start sounding notes on your instrument.
Of course IMHO.
