<html> <body> Hi Conrad,                      I have had more than one pianist, use the una corda at forte,  purely to get the timbre  difference.   Using the pedal this way is particularly useful in repeat passages, just to give a slight difference with out changing dynamics. Regards Roger <blockquote type=cite class=cite cite="">Try an experiment.  Have a pianist play a phrase at mezzopiano without using pedals at all. Then have them play it at the same volume but using a fully engaged (i.e. fully missing one string and getting strings back to grooves) una corda pedal. I feel confident that you will hear a difference.  Desirability and/or noteworthiness thereof are purely subjective. Just for grins, I did a similar test with the RCT Pianalyzer. Definite difference. partials: [YMMV] Fundamental - ~ same Octave      - ~ 20% less 12th        - ~ same double 8va  - ~ 40% more tierce      - ~ 40% less quint       - ~ 40% less 7th         - ~ 60% less Just one note... {YamC7 middle D} Imagine these differences over the scale. a definite change of timbre available which the fingers alone cannot duplicate. This is a static comparison. I don't have equipment which would give a representation of the development of the sound envelope which, since the third string is driven by the two, would also show a definite difference.

It's gone right now and didn't leave a forwarding address. _______________________________________________ caut list info: <a href="https://www.moypiano.com/resources/#archives" eudora="autourl"> https://www.moypiano.com/resources/#archives</a> </blockquote></body> </html>
