## Where should I start with ear training basics?
The curriculum places Chords & Harmony before this module. Review those topics if they are unfamiliar. The first lesson is “Introduction to Ear Training”: Why hearing matters as much as reading. The order is a study guide, not proof that every learner needs the same pace.

## How long is the ear training basics module?
The 4 listed lessons total approximately 54 minutes of material. That estimate describes lesson content, not the practice time needed to become comfortable with hearing what you see, seeing what you hear. Revisit one task at a time and use feedback from a teacher where physical technique is involved.
