Two Voices at Once
Double stops and broken chords
When you play two strings simultaneously, the cello becomes a duet with itself. Learn the mechanics of intonation in parallel thirds, sixths, and octaves, and how to voice broken chords so the melody sings through.

Planning this part of your learning
- Where should I start with two voices at once?
- The curriculum places The Flying Bow before this module. Review those topics if they are unfamiliar. The first lesson is “Thirds”: Parallel thirds, the most common double stop. The order is a study guide, not proof that every learner needs the same pace.
- How long is the two voices at once module?
- The 5 listed lessons total approximately 69 minutes of material. That estimate describes lesson content, not the practice time needed to become comfortable with double stops and broken chords. 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 two voices at once 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. Later lessons require the relevant paid package.
