This article is the fourth installment in a series focused on building a guitar theory app. It introduces the CAGED system, centering on five foundational open chords: C, A, G, E, and D. Mastery of these chords is essential for progressing to more advanced applications of the CAGED system. The article details the creation of a new page displaying these chords using TypeScript for type safety and effective rendering. It also outlines the modeling of note positions and the structured mapping of finger placements on the fretboard, laying a groundwork for future development.
The CAGED system serves as a fundamental approach to guitar theory, anchored by five open chords â C, A, G, E, and D. Mastering these shapes is crucial for advancing.
By establishing a chord type with TypeScript's as const, we enhance our coding process, allowing for type safety and effective mappings for chord rendering in the application.
