- Mirror mode reflects primes around middle C, alternating above and below.
- C Major mode maps primes onto degrees of the C major scale.
- Harmonic mode turns each prime into a chord (root + major 3rd + 5th).
- Spiral mode walks upward through the keyboard cyclically, like a spiral.
- Factors mode uses the number of prime factors to determine chord size and richness.
