| Signs of a need of regulation include: | |
 |
|
Hammers at uneven blow distances | ||
| Uneven key heights | ||
 | ||
|
Notes that will not repeat well,
Notes that repeat when you do not want them to, Notes that sound quiet, Notes that continue to sound after you have released them, Notes that give a muffled sound but do not ring, Notes that do not always work and, for the expert player, unevenness of touch. | ||
