Why does the trainer use simplified enharmonics?

Practical music theory study often requires simplification. Our trainer focuses on intuitive exercises by using a system of simplified enharmonics.

We reduce all notes to their natural equivalents on the keyboard. Your benefits:

  • Instant Orientation: Instead of analyzing the theory of B♯, you immediately press the C key.
  • Mental Pitch Map: You build a map in your head that corresponds to the physical instrument, facilitating reharmonization.
  • Faster Transposition: Your learning becomes more practical and efficient.
