Guided Professional course · 16 attempts
Professional training with a sustained drone and just minor thirds above changing roots. The goal is not slow visual correction, but fast, controlled placement inside a narrow target zone.
Professional challenge: maximum 10 seconds per attempt, target zone ±8 cents. Pass with at least 14 of 16 attempts. Stable detection uses the pitch engine’s Professional lock.
How this is assessed
The attempt only counts as passed once you hold the target pitch steadily in the green zone for 1 second.
Timing starts with the microphone. After a hit, the feedback sound plays fully, then you continue consciously.
Quickly choose whether you want to sing or play. The current task then restarts in a suitable range.
This selection is used as your default and can be changed again before any course task.
