SUGGESTION: Play each scale that you know and recite each note as you play it while glancing at the fretboard, then, before moving to the next note glance at that note on the staff. For example, you already know that middle C is located on the 5th string, 3rd fret AND that it is also located on the 6th string, 8th fret. Practice the C major scale in both positions while reciting and glancing. Next, practice C major (reciting/glancing) in both positions but, start each scale at the top. GO SLOWLY, AT FIRST. After you get comfortable with the approach, try the same (recite/glance) with other scales that you already know. Don't forget to give us some feedback, as to your findings.
