I Saw Her Standing Thereby Beatles

I Saw Her Standing There is a billboard chart topper released by Beatles on their 1963 album "Please Please Me". This one has a unique timbre because it incorporates sort of a dominant sound in the introduction, using pentatonic licks to fill in the space between chord hits. It's mostly split between two guitar parts. One plays a rhythmic role, holding it down with broken up low notes and chord hits that mimic a bass and piano player. The other guitar part has a repetitive riff that creates movement in the background for the vocal melody to ring out over.
