BASIC INFO- the guitar is a plucked string instrument that can be played with fingers or with a pick. usually, the guitar has 6 strings. although, there are others that can come in 7 string, 12 string, and 4 string, to name a few.
TYPES- obviously, there is the ACCOUSTIC GUITAR- wich has a sound hole, that when played, noise vibrates out the hole. and the ELECTRIC GUITAR- that when played, the noise comes out of an amp. But, there are also many more types of guitars, to name a few, RUSSIAN GUITAR- a seven string accoustic usually tuned to open g major. TENOR GUITAR- a slightly smaller four string guitar that is tuned to fifths.
TUNING- the common guitar tuning (standard tuning) is EADGBE, for a slightly heavier sound (used lots in grunge) you can go with D#/E♭ tuning. (half a step down) it is used by bands like, nirvana, green day, guns N' roses, van halen, jimi hendrix, and alice in chains. and if you really wanna fuck up your sound, you can bring your guitar ALL the way down to octave tuning. at this point in tuning, you might as well buy a bass guitar.
