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.

Here is a cool riff from Tull that has quite a bit of technique that all guitarists need to know. The ribbon-like symbol in the first and second measure is known as “vibrato.” This is when you rapidly shake the string being played with your fret hand. There are also a few slides, which are performed by sliding your fret hand on the strings while playing at the same time.
