Is this trainer only for keyboard players?
Absolutely not! The piano keyboard serves as a universal interval map. It is the clearest way for guitarists, bassists, and vocalists to understand music theory. The logic is identical across all instruments.
Does the trainer help with reharmonization?
Yes! By practicing scale degrees, you learn to think in functions (e.g., "replace 1 with 6m"), which is the key to creating new arrangements.
How does the trainer support guitar learning?
NNS is the foundation of modern guitar. The app helps you translate numbers into notes on the fretboard instantly.
