Listen for timing
Check whether note spacing stays steady through each finger transition, especially 3-4 and 4-5.
Evenness is not just playing the notes in order. It is keeping timing, tone, and motion stable enough that repeated passes sound and feel comparable. In Hanon, that matters more than reaching a headline tempo early.
Check whether note spacing stays steady through each finger transition, especially 3-4 and 4-5.
Notice whether certain fingers strike harder, thinner, or later as the pattern continues.
One clean pass is not enough. The next few runs should resemble it closely before tempo changes.
Choose a speed where the pattern stays controlled enough to expose unevenness clearly.
Keep the exercise, fingering, and tempo fixed for several passes so you can compare like with like.
Adjust one technical variable before the next pass, then check whether the same instability improves.
