Ha! Ironic! Sound reducing earplugs, to better hear sound! That actually is what worked for our band, (our on stage volume), as now, we mic everything, thus not needing to push our amps out to the people. The PA of course does that, (as most bands use that system).

Less sound heard,,,,,,,to hear more music! Hmmmm!
It's all in the details, for sure! And they are usually hidden within. Once found, look out! Works for those world class pianists I talked about, and in every musical situation for all of us, if we allow it, that is.

The tough part is to control exactly, the three finger chords and more on the keys, for those reaching of the black keys, however so slightly that is for any given chord with sharps. Even a C chord, or a Dm, or Am has to be played carefully if wanting one or two of the notes to be brought across more than the others. Or for when the same.

Unless it's ROCK! Ha! But Rock by great bands will still find careful dynamics, if we listen for them, that is!

Thanks again for asking my thoughts on the keys.
