You will hear short melodic patterns. Your task is to determine whether the current pattern matches the pattern you heard N positions back.
For example, in 2-back mode: Does what you just heard match what you heard 2 patterns ago?
Controls
MATCH — Press when the current pattern matches the N-back position. NO MATCH — Press when it does not match.
Keyboard: M = Match, N = No Match, Space = Start/Stop
What Counts as a "Match"?
Here is where this training differs from ordinary memory tasks. The exact notes you hear will be different every time. You are not listening for identical sounds. You are listening for whether two patterns share the same underlying structure.
We have intentionally not described what these structures are or how many exist. Discovering them yourself is part of the training. Your task is to perceive the relational shape of each pattern and hold that shape in memory.
Why This Matters
This is not a memorization task. It is training in relational perception — the ability to extract abstract structure from concrete experience. Because the surface features (actual notes) are always novel, you cannot rely on rote memory. You must engage the deeper pattern-recognition capacity that underlies fluid intelligence.
Tips for Beginners
• Start with 1-back or 2-back to learn the rhythm.
• Use Practice Mode first — it shows feedback without scoring.
• Don't overthink. Let your intuition recognize the shapes.
• When you notice confusion, observe it. Which positions are you conflating?
• Enable Breath Sync to help anchor your attention rhythmically.
