Increase after repeatability
One clean pass is useful evidence, but several similar passes are what justify a change.
Tempo should move only after the current speed is established. In serious technique practice, a faster marking is not a reward. It is a new assignment that should arrive after accuracy, stability, and consistency have already held together.
One clean pass is useful evidence, but several similar passes are what justify a change.
A modest bump keeps the hand organized and makes regression obvious instead of confusing.
The next tempo should answer a clear question about control, not satisfy impatience.
Choose a speed that reveals unevenness without creating tension or emergency adjustments.
Keep tempo, fingering, and assignment fixed long enough to tell whether the result is consistent.
Use a small increase, then look for the same control before deciding that the faster speed is established.
