<html> <body> Mrs. Gottshall, Temperaments are interesting and tuning to one will reveal different things in the music.  The more flavor (read digression from equal) the less portable the intervals become especially for modern composers.  I had Barne's Bach on (formerly) our little Wurly by Samick and it made the piano sound sweet and the extra consonance made it seem more powerful.  Debussy just plain ground on that temperament though. As Ed pointed out, Beethoven's pedal marks work with a temperament containing less dissonance than equal does.  I tuned our piano back to equal as my wife prepared a recital featuring late nineteenth and twentieth century composers and it sounded very dissonant to us for a while. There is a point to consider though.  The modern piano sounds quite different to the pianoforte of Beethoven's day.  It has more inharmonicity and power.  This isn't without consequence.

Or would the difference be negligable / inconsequential between that temperament and our latest truly equal temperament?    Me thinks I would hear the nuances of going from the key of c#minor to the key of Emajor within a mouvement.   Seeking opinions and /or personal experience with this sort of thing.            Also. business is finally, after 39 months, getting to be NOT hand to mouth anymore!  It's getting pretty good,  and (YippEEEE!!!) me thinks I am going to be able to afford to go to the Eastern Regional PTG Conference in 2007. I am looking so forward to meeting my senors / mentors on this list, who have graciously advised and encouraged me with my piano questions!   Thank You!
