¡Bueno! I don't know ...not cold... I've been concentrating and can reckon notes but to say I know each note as I'm playing would be false.... I'm recording an exercise I found in a Steve Vai book where he randomly lists each note of string. So "F# on B string, C on D string" etc... You play it back and hit that note asap! Hopefully it leads to greater understanding of music. How bout you? How quick could you find C# on the G string? How about finding all the D notes on the fretboard quickly? Any other exercises to learn the fretboard? It's amazing how few effective means I've found..
