Jack proceeds to demonstrate how to identify and play these arpeggios in various positions on the guitar neck, using the "CAGED" system as a reference point. He offers practical exercises to help viewers internalize the shapes and sounds of these arpeggios, suggesting ways to practice them across all six strings in different positions. Jack emphasizes the importance of learning these arpeggios thoroughly in one position before moving on to the next, ensuring a solid foundation is built for improvisation and melody construction.

Throughout the masterclass, Jack shares his insights on applying these arpeggios musically, encouraging viewers to integrate them into their playing deliberately and with intention. He highlights the versatility of arpeggios in navigating chord changes seamlessly, regardless of the musical genre. By the end of the session, viewers are equipped with a comprehensive understanding of seventh chord arpeggios, ready to explore their creative potential on the guitar. Jack concludes by promising to make a backing track available for practice, further aiding the viewers in their journey to master the art of arpeggio-based improvisation.
