I bought a guitar FIRST THINGS I SHOULD KNOW?

Well, if you know nothing about guitars, you probably didn't know what to look for. The first thing to look at is the setup. Are the strings nice and low on the fretboard? Does it hit the other frets when you press down on certain frets? What king of guitar, what size strings... it all makes a difference on how well you will be able to play, and whether or not you WILL play, a guitar that hurts your fingers way too much won't get played. After you get the guitar itself sorted out, then you need a good beginners book WITH a DVD, and a guitar tuner, like a Korg, about 15 to twenty bucks. A guitar that's not in tune is about worthless. There are alternate tunings than "standard" however. What kind of music do you wan to play? Best to stick with standard tuning for now, since all books are geared toward standard tuning. IF you're not going to get lessons from an actual teacher, find somebody that can already play fairly well and have them show you the basics. Learning basic chords early lets you strum along to a wide variety of songs. You really shouldn't use tabs to learn, but for some, being able to actually play a real recognizable tune helps keep them motivated, I say what's the harm if it's not the ONLY thing you learn.

A "cord" is a cable used to connect a guitar with a pick up to an amplifier. Do you mean "chord"? If so, can you play the chords you know the name of?

I am afraid that there is no "easy" way of learning to play the guitar: it requires a lot of effort and time.

Frankly, I can't understand anyone buying a guitar without being prepared: without finding out as much about it as possible and without having what they need before actually getting a guitar. I learnt to play over forty years ago in the "dark" ages before DVDs, You Tube, The Internet and endless numbers of guitar magazines and yet I knew about the different types of guitar, how, physically, a guitar was played, the names of the parts of guitar and related vocabulary (e.g. "chords"), what notes the open strings were tuned to, the names of the notes on the treble clef etc. I had a set of pitch pipes (no tuners in those days), picks and spare strings and a beginners' guitar book. Most importantly, I knew it would be HARD; I didn't expect it to be easy.

I think that's what you should have done. I really wouldn't want anyone to know I'd actually spend money on a guitar but knew "0%" about guitars! If you really want to learn tp play, lessons from a GOOD teacher are best. Second best is a good beginner's guitar book or books which you need to work through thoroughly.

Yep, its a case of repitition is the master of skilfulness wen it comes to guitar playing,

as your starting off, practice for 30 mins a day, with getting used to playing chords, looking up some music theory as you go along like scales and reading tab.

wen your fingers start to get used to it, extend your practice to 1 hour a day, then after a year, extend it to 2-3 hours a day, keep it going and watch your skills grow
