Open up audio for the riff and follow the tabs. Open the song that you're covering in another window on your internet browser. Play through the song and trace the chords and notes with the tab that you looked up. Try to follow the numbers on the tab with the notes that are being played in the song. Try to get an understanding for which chords the artist is playing before trying to duplicating it.
If you just want to learn a few chords to strum along to some songs, then learning to play the guitar really isn't that hard for most people. Many students are able to learn a few chords and get a decent strumming pattern going after a few weeks. If you've had prior experience playing an instrument, you can expect to pick it up after just a few lessons.

I would especially like to stress the gentle approach Justin takes with two key aspects that contributed to my development as a musician - music theory and ear training. Justin has succeeded in conveying the importance and profoundness of understanding music both theoretically and through your ears while maintaining a simple and accessible approach to them, all while sticking to what is ultimately the most important motto: 'If it sounds good, it is good'.
Practice at least 20 minutes 6 days a week. Consistent practice will allow you to improve your guitar playing skills over a short period. Taking long breaks and not staying dedicated will wear away your muscle memory and delay the development of your skills. Instead, dedicate 20 minutes to an hour of practice throughout most of the week. During practice, you can either run different drills or you can try covering a song.[14]
Intermediate Guitar Class - Open to all ages, from age three to one-hundred sixty-three, but an audition or permission from the instructor is required. This class is intended to be challenging.

New classes start every month and may be repeated as often as you like. Cost is $85 per month (4 hours).
