First you have to tune your guitar, otherwise it will sound horrible. =)Tune with a computerized guitar, Click here
Warming up before might sound a little stupid, since we are "just going to play guitar" - we're not going to run a marathon or anything...
However it is actually very good, and you will notice a big difference whether you warm up or not as to how your guitar performance is affected! The warm up helps:
1. To get some blood flowing to your virtuosic guitar fingers
2. To get your muscle metabolism started, that way they won't tire out as fast
3. To soften up the joints
4. To prevent musculous or tendinous strain.

Now there are many diferent ways in which you can do this, however I like to keep is simple. I usually just:
1. Do the hand-shakes
2. Do the ball
3. Do the stretch
Also some massage on the palm of your hand, as well as the underside of your forearm is helpful, with focus on your fretting hand of course (these are the muscle groups that will be involved mostly)
I will demonstrate this to you in the video.
Also I'd like to add that exaggeration of these movements (quite obvoisly) might hurt your arm, and it might even lead to slapping someone nearby in the face. So take it easy =)
These warm-up exercises are particularly useful when you start playing bar chords, believe me.
Time to make use of the chords of the previous lesson! We are going to play a song in which these specific hords are actually used - Sweet Home Alabama. I'm sure that you have all heard about it, however if you did not, check it out on YouTube or something.
I have composed a simple bassline completed with the main "solo" riff from the song (that we all know so well), in guitarpro (guitar tabulature software) that we are going to have as a backing track for playing the chords.
Playing in four-stroke measure means that we are going to strum the guitar 4 times each measure. But what is a measure then? Well - have a look at the picture:

If you strum the guitar each time you count, you will be effectively playing in four stroke measure..
Just in case I am a little unclear - I will show you in the video how to do.

Notice that I only play downstrokes in the video. In this case I believe it is what makes the best sound for playing in this particular way, and I suggest you learn the same way for this particular way of playing the song. In the next lesson I will show you a little more advanced and better-sounding way to play the song, which will utilize both up and downstrokes.

You may already at this early stage try to sing along with your music. This, however, is an art that takes quite some time to master. I could not do this properly until 1-2 years of playing, but if you give it a good go it should not be any problem for you (your simultaneous capacity surely exceeds mine;)). If you hear me singing in the video, be aware of that I am not a pro singer, and that it may sound awful.
Here's the chorus for the song. You can actually almost play the entire song with this chord pattern, but it changes a little here and there, but I'm not going to go through that at this point.
Sweet home Alabama
Where the skies are so blue
Sweet Home Alabama
Lord, I'm coming home to you

New lesson - new chords. In the next lesson we will have a chord repitition, so make you you learn how to grip 'em and strum 'em neatly!

You can already try to play this song by yourself, to keep practicing. If you find it too difficultn ow, return to it later
That's all for this lesson, before you move on to the next...
