Greg Tony Caught wrote: <blockquote TYPE=CITE><style></style> List A music teacher in Darwin has just bought a new Ronisch piano. Approx. 125CM high, made in Leipzig, Germany by ???. Not Ronisch. Has a Renner action, lovely cabinet but the bass. I can't say lousy choice of piano, she paid cash to a major store in Sydney, played the piano several times before deciding, all the right things but. I tuned the piano yesterday (raised pitch from 20 cents to 65 cents flat) and she played it after and said 'C1 doesn't sound right' Checked it by ear and all is OK, asked her what she thought was wrong to which she replied that it 'sounded more like a G note' asked her how her pitch recognition was to which she replied 'pitch perfect' switched on computer and clicked onto the new TuneLab Pro, played C1 and checked the partials. Partial 3 = 100 partial 4 = 45.. Showed this to customer and explained that the fundamental is very low (absent) in the lower bass but the harmonics are very rich, what she is hearing is the 3rd harmonic of C which is G. Tuned the note up, she tested, tuned the note down, she tested, put it back where it was, she tested and said now its OK. I didn't like the scaling of the bass, the treble was OK but the bass ? Question. Why is this C1 note so heavy on the 3rd partial and so low on the 2nd and 4th. And, how can you increase the 2nd and 4th to make it sound like a "C" note. ? Tony Caught ICPTG Australia <a href="mailto:caute@optusnet.com.au">caute@optusnet.com.au</a></blockquote> -- Greg Newell Greg's Piano Forté 12970 Harlon Ave. Lakewood, Ohio 44107 216-226-3791 <A HREF="mailto:gnewell@ameritech.net">mailto:gnewell@ameritech.net</A>   </body> </html>
