The keyboard won't level itself😄
And a level keyboard is the foundation and basis of aesthetic pleasure!

But first and foremost, adjusting the mechanism - the source of physical pleasure from the proper operation of the keyboard and hammers!

The hammers themselves and working with them - at the end! Their final alignment, straightening, shaping, and voicing to improve the instrument's timbre!

This is already top level and great responsibility ☝😑
