This riff is in 4/4 time except for the 2nd measure in which we switch to 2/4 time (only 2 beats).
Notice that the 4th measure mirrors the 1st measure, but with the addition of bends. This is a typical Jeff Beckism. It may be tricky to get it to sound right because it relies on precise bending.
This is a really easy lead. If you have little or no prior experience playing lead guitar, this would be a great start!
You should have no trouble playing this riff at all. For the most part, the two guitars play the same thing, except for the bend at the end of the measure. This riff is set to a standard 90 bpm (beats per minute).
