We know that the longer the key, the more docile it is. What advantage is obtained by progressively decreasing its length? To be able to have a smaller stroke on the high notes?

Exactly. For what reason do some grand pianos adopt the fan-shaped keyboard?

Maybe I didn't explain myself well. I know very well that a greater length is better. So why not make the highs "long" as well?

but why do the hammers weigh much less in the high notes, and the leverage should even be counterbalanced (as is generally the case in all pianos for the last two high notes). In some, the difference is minimal. One must then see from brand to brand.
