A simple question

I look at the fretboard.  Not all the time, not when playing cowboy chords and easy stuff like that.  But when doing any lead or when jumping up to barr chords higher than the 2nd fret etc, then ya, I glance down. lol.

To be fair, I almost never just play guitar.  I'm always singing, looking at my lyrics (cuz my memory is terrible, I need my lyrics and chords!), sometimes looking at other band members to give some sort of non-verbal physical cue, and potentially engaging a small crowd of some sort. Even when recording, I'm looking at specific stuff on the studio or now the DAW whilst recording. A lot going on in my head.  So I glance down at the fretboard a lot to just make sure or calibrate myself periodically.

I'll be the first to admit, I'm no prodigy; far, far from it.  I need to look down at a lot of stuff to help me perform.  I think I have a total of about 3 songs I can play from memory without anything to help.  That's out of my song book of around 300 songs!  LOL.   Even with that, one of those songs, where I have to work my way up to the 7th fret once each verse, I look at the fretboard every time I do it or I promise you, I'll miss that 7th fret by some sort of margin!  LOL. 

I don't know, it isn't something I am conscious about.

Is it something one should do or not do.

Maybe if you keep hitting the wrong notes you should look more often.

I think some might also look at the guitar whilst playing just cuz it looks cool.  LOL.  I remember Jimmy Page and Slash and others etc doing it all the time on stage and me and my friends always thought it looked cool and even mimicked the way they did it.  

So, ya, there's that too.
