These videos are designed for guitar beginners or those with only limited guitar knowledge. They use simple chord shapes as much as possible and do not necessarily represent the way in which the song was originally played. They are designed as practice tools to supplement your other learning methods. Information is provided on screen for both right and left-handed players!
Lottery is played with a capo on fret 2, but to be honest it's almost easier to play it without one. Jade uses barre shapes, but without the capo you could just play an open A major and Dsus2 chord for the verses and chorus (with a Dm on the end). For the bridge you could then use an E major and a B minor.
Jade keeps her index finger flat across all 6 strings for both the G and C chords. You don't need to strum all of the strings in the Csus2 chord, the high E and sometimes the B are often missed.
