Hmm, that would make Beethoven's Piano Concerti plonk down at a level close to 1. I once was at a "concertante lecture" where a piece was played called "Grande accorde cromatico" (or something like that), consisting of playing 1 time all 88 keys
at once. Guess your plokometer would go boink?

I have not heard any of his music and was basing my comments on the little write up on Wikipedia.
You are actually doing a plinkouisity-estimate based on a Wiki-line?? Wow....
Where did you find this recording??
You must have misunderstood me. I found the
title "Pianoconcerto in E-flat major" to sound rather unplinkive. There aint no recording. So, if anyone at BIS or ONDINE or CPO is reading this, all three concertos should easily fit on one CD.
I started to collect Finnish Piano Concerto scores
Do you have the (rather tragic) Mielck's "Concert Piece" for Piano and Orchestra? It is a concerto, really. (NB: not the piece is tragic, but Mielck's fate is, or was).
I rermain curious as to why a plOnkometer measures degrees of plInkiness.
Well, tape measures measure more than tape, and an odometer does measure more than the lenght of Odo...
All best,
