Music theorists and educators struggle to accurately name and teach complex jazz chord extensions

Musicians, music teachers, and jazz students lack clear, standardized guidance on naming advanced chords (like 13th chords on non-root scale degrees), leading to confusion, inconsistent notation, and difficulty communicating harmonic concepts. Existing music theory resources don't adequately address the specific rules for naming chords built on scale degrees other than the root, forcing practitioners to spend hours researching or making educated guesses that may be incorrect.
