Musicians struggle to understand and analyze complex classical music chord progressions

Musicians and music students encounter difficulty deciphering the harmonic structure of classical compositions like Bach's BWV 846, lacking clear resources to break down chord progressions in a way that aids learning and performance. Current music theory resources are either too academic and dense or too simplified, leaving intermediate musicians frustrated when trying to understand the specific harmonic choices in canonical works. This gap forces them to spend hours cross-referencing multiple sources or hiring expensive music theory tutors.
