Planning this part of your learning
- Where should I start with diatonic harmony & roman numeral analysis?
- The curriculum places Rhythm Mastery & Complex Meters before this module. Review those topics if they are unfamiliar. The first lesson is “Roman Numeral Analysis”: The universal language of harmonic function. The order is a study guide, not proof that every learner needs the same pace.
- How long is the diatonic harmony & roman numeral analysis module?
- The 6 listed lessons total approximately 88 minutes of material. That estimate describes lesson content, not the practice time needed to become comfortable with chord functions, harmonic rhythm, and voice leading basics. Revisit one task at a time and use feedback from a teacher where physical technique is involved.
- What can I try here without an account?
- The diatonic harmony & roman numeral analysis description, lesson sequence and prerequisite links are public. There is no full worked lesson sample for this module yet. The linked public tools and references are free. A free account includes the complete five-lesson foundation module in each instrument and five lessons in music theory, with saved progress and no expiry.
