You will often hear different opinions about how guitarists should or should not finger certain passages. Some might even allege that there is always a proper guitar fingering for each musical situation. Maybe you find yourself falling into this way of thinking.
For example, you might think that it’s more “correct” to use the pinky, or at least it’s a bad habit to avoid using it. Many players, including Stevie Ray Vaughan, Eddie Van Halen, and Eric Johnson, however, are famous for doing most of their guitar soloing with just the first three fingers. I tend to favor these three fingers as well, especially when using pentatonic scales, although I do use my pinky in my instructional guitar videos to make it easier for the viewer to see where I am fretting the notes.
Obviously the idea that there is a universally correct and proper fingering for guitarists to use with everything is not true. You have to find the fingerings that work best for you. If you play well, and sound good, then you’re using the correct fingering!
