If you're a beginner guitar player you may not have learned this open G7 chord yet. Well, time to get to it, right! No huge tips on how to incorporate it into your playing except two simple ideas:
If you've got a song that starts with a C Major chord (in other words is in the key of C Major) you could use the G7 instead of a G Major chord. Or if you already have a song that has a G Major chord for a full bar or long try alternating to the G7 during that bar.
