I'm trying to understand the techniques used in this piece. Am I right in thinking that what Tori is really doing here (in the right hand) is just playing riffs mainly based around the A minor pentatonic (with occasional extra note, 9th, #f on the IV) using drones on the 7th and 5th degree of scale and 4th, 5th and 6th intervals, rather than following the underlying harmony?
