Watch the Elements In Sheet Music online guitar lesson by Rich Maloof from Acoustic Guitar For Beginners

Music can be represented on the written page in several different ways. And when a piece of sheet music also represents where a guitarist should put his/her fingers, the page can look like a bunch of hieroglyphics. None of it is really very complicated though, so let's look at the elements commonly used.
CHORD GRIDS - graphic representation of the guitar neck, showing where to place your fingers
SLASH CHORDS - a chord name separated by the bass note to be used, such as G/B or Am/G. Sometimes the slash is spoken as "over" - as in "G over B" or "A minor over G"
CHORD NAMES ABOVE LYRICS - refers to the chord grids usually
TABLATURE - a graphic system for representing notes on the neck of the guitar
MEASURE or BAR - unit of time comprised of a fixed number beats
RHYTHM SLASHES - Basic way of showing beats or strums
