<html> <body> Terry, I'd suggest contacting Jim Reeder. He's a Bluthner dealer and also a rebuilder. He helped me once on one I had to tune (my first one). <a href="http://www.reederpianos.com/" eudora="autourl"> http://www.reederpianos.com/</a> Avery At 01:27 PM 8/1/05, you wrote: <blockquote type=cite class=cite cite="">I had someone reply to me privately on this subject. He suggested something that no one else had mentioned.   "...there are two sections with the extra string. in the lower section you tune the fourth string an octave higher than the notes to which they correspond and in the upper section you tune the extra strings in unison to the strings below."   This information reportedly came from a Bluthner dealer. I'd sure hate to be wrong and start breaking strings. Anyone else ever hear of this? Is there any possibility that there were different scales that were tuned differently?   Terry Farrell <dl> <dd>I just booked a first-time tuning for a Bluthner grand (first time for me to tune it). It is said to be about 55 years old. Is this piano likely to have the 4th string aliquot system up in the high treble? If so, is there any special tuning techniques for it? I've never tuned one of these. Just pluck it and tune it beatless with the other three strings of each note? <dd>  <dd>Terry Farrell </dl></blockquote></body> </html>
