Music is way more than connecting the written notes...
Musical times had two dimensions and two flowing directions not one dimension and one direction as physical time...Thermodynamic dont govern musical world...
No written score can display the method and the means to translate these two interacting dimensions...
The artist must touch the vertical time with his heart , going there or/and coming from there , for the melody to be born and live without dying in the horizontal metronomical measurable time ...
This pianist plays with his pulsating heart sounds coming and going from physical time into vertical time.... The melody surge from his hand/heart not from the written score at all and anyway dont grow in the horizontal time as all Scriabin piano works...very diffricult to play , not so much by the virtuosity asked for but by the pulsating vertical dimension which must be manifested...
For me as i feel it, rythm is in the horizontal time direction but expressive pulsation is on the vertical direction...Rythm flow but varied pulsations dont flow they surge as the playings grow... It is difficult to put in words... 😊 I am not a distinguished musician as the OP but a listener... It is my experience only...
For sure when we live in musical time feeling it, the sound quality dimension is secondary...Music is meaning embodied in sound, as our soul is embodied here...it is better tob have a beautiful body with a beautiful soul...
