Breaking down the key guitar elements from The Beatles' "I Saw Her Standing There." I demonstrate John Lennon's signature E7 chord voicing - if you know your C7 chord shape, just slide it up four frets so the root note is at fret seven. This creates that open, characteristic sound.
George Harrison's E7 chord uses a D7 shape moved up two frets (4-3-4 pattern), creating that inverted triangle shape that always happens with seventh chords higher up the neck. These two different E7 voicings are the main guitar takeaways from this song.
The iconic bassline uses the notes 0-0-4-0-7-0-0-5-4 on the low E string. Those notes at frets 0, 4, and 7 are the three notes that make up an E chord triad. Understanding where these triad shapes are across the neck is essentially how you play intermediate or advanced guitar.
The improvised solo section uses E minor pentatonic all over the neck. If you want to practice this concept, "Shakin' All Over" by Johnny Kidd and the Pirates (available in Intermediate Electric) is a great song that teaches you E minor pentatonic positions across the entire fretboard.
