You break into a nervous sweat.
"Oh that one? Yeah that's the 6th fret on the D string."
"Yeah I see that but what is the name of that note?"
(buying time) "This note right here?"
(becoming impatient) "Yeah, that note right there."
(guessing)"Um... It's a cool note, it's called... Uh... F minor?"
"POSER! I HATE YOU!"
You blew it and now you revel in shame. All those hours spent practicing, and the names of the very notes you've mastered have eluded you once more. NEVER AGAIN!
Regardless of what instrument you play, there are only 12 notes in all of music, and they repeat at higher or lower pitches. They are as follows:
A - A#/Bb - B - C - C#/Db - D - D#/Eb - E - F - F#/Gb - G - G#/AbAs long as you know that order, you can count off from any open string to find the name of any note on your guitar. Now, that may seem daunting as most guitars have upwards of 120 different places to play those 12 notes. Never fear! It's not necessary to memorize every single fret on the neck, in fact, you only need to learn a couple and then find out how to use different tricks to spot that same note elsewhere up and down the fretboard.
