This tune is a great example of how to take full advantage of the guitar's register to sit into a band properly. As you'll notice in the first half of the song, I'm mainly playing the upper part of the chords or using single note lines instead of full barre chords. This gives us the opportunity to leave space for the vocals and bass guitar. By avoiding the low strings at the beginning we can keep the part lighter and more airy, keeping it simple as if there was a vocalist singing. All too often I hear guitar players playing too much and messing with the vocals. Imagine if you were soloing and the singer was singing over what you were doing—it's basically the same thing.
By thinking about register and starting off small, we can take the song in many different directions. Listen to the original recording of this tune by Led Zeppelin as an example.
