In theory, all piano scales should probably be called triplex scales since there are really three working parts to each scale. Usually, though we seem to think of them in terms of just two segments at a time: the speaking length and the frontscale or the speaking length and the backscale. Some scales have one or more of the duplex string segment(s) “tuned” to some (theoretically) specific partial of the fundamental speaking length. In these cases the duplex string segment is an “aliquot part” or a “fractional part” of the whole. This can be either the frontscale or the backscale (or both).<o:p></o:p><o:p> </o:p>ddf<o:p></o:p><o:p> </o:p>Delwin D Fandrich<o:p></o:p>Piano Design & Fabrication<o:p></o:p>6939 Foothill Court SW, Olympia, Washington 98512 USA<o:p></o:p>Phone  360.515.0119 — Cell 360.388.6525<o:p></o:p><a href="mailto:del@fandrichpiano.com">del@fandrichpiano.com </a>— <a href="mailto:ddfandrich@gmail.com">ddfandrich@gmail.com</a><o:p></o:p><o:p> </o:p>From: pianotech-bounces@ptg.org [mailto:pianotech-bounces@ptg.org] On Behalf Of Alan Eder Sent: Thursday, March 08, 2012 10:53 AM To: pianotech@ptg.org Subject: Re: [pianotech] Early Duplex Scale<o:p></o:p><o:p> </o:p>So the name is NOT "aliquot"? <o:p></o:p><div><o:p> </o:p></div><div>Alan Eder <o:p></o:p><div>-----Original Message----- From: David Boyce <<a href="mailto:David@piano.plus.com">David@piano.plus.com</a>> To: pianotech <<a href="mailto:pianotech@ptg.org">pianotech@ptg.org</a>> Sent: Thu, Mar 8, 2012 10:36 am Subject: Re: [pianotech] Early Duplex Scale<o:p></o:p><div id="AOLMsgPart_1_56bf4702-36da-44cf-b1f2-bb449f211c9c">Oh that's interesting Jurgen, thanks. Let's settle for them being Rosewood then!  Still nobody has a name for this piano part! Is there a name in German? How would it translate in English if so?  Accordinmg to Allen Wright, Steinway just called them "duplexes".  Other makes must call them something, when they are ordering them in the factory! <o:p></o:p><div><div name="Compose message area" id=MailContainerBody><div>I have a 1911 Rönisch<o:p></o:p> grand that has a rosewood hardwood rear bearing strip,<o:p></o:p> but it is continuous.<o:p></o:p></div><div> <o:p></o:p><o:p> </o:p> <o:p></o:p></div></div></div><div>Jurgen Goering<o:p></o:p></div><div><o:p> </o:p></div> Best regards, David. <a href="http://www.davidboyce.co.uk" target="_blank">www.davidboyce.co.uk</a><o:p></o:p></div></div></div></div></body></html>
