This Beatles song starts with a pretty awesome pentatonic lick that will help you work on your stretching in your fretting hand, while simultaneously keeping your rhythm on point.
In ¾ time signature it requires a different feel than a standard 4/4 song (very common to the Beatles).
Following that intro riff come a series of chords using a similar rhythmic pattern that are overdubbed by with some killer country-blues style licks to help keep the momentum moving.
It winds it’s way into the guitar solo which is chock full of great 60s style blues licks with a rapid and accelerated ending to help cap it all off.
All in all, if you’re looking for a Beatles song with versatility and some licks that will challenge you, then this is your song!
