List and Bob, The fact is that there's not too much fundamental to measure in the bottom 1 1/2 octaves of any piano. Using TuneLab, the lowest fundamental I've been able to detect on any good piano is C1, and the consistently detectable range starts at about F1. A usable fundamental for tuning probably does not occur much before C3 in most pianos. If the low bass is a little thin, the problem is almost assuredly not the lack of fundamentals. Frank Weston ---------- From: Unknown <rls@ncinter.net> To: pianotech@ptg.org Subject: Fundamentals Date: Wednesday, June 17, 1998 10:03 PM Dear list, This Sunday at our local chapter meeting we employed an RCT to analyze the partials in the low bass on my 1911 S & S "O". The graph showed absolutely no fundamental on the lowest 1 1/2 octaves. One of our members who works at the local Story & Clark factory suggested that there might be a problem with the downbearing at the back side of the bass bridge. Keep in mind that this piano had a new board and bridges installed by New York Piano Center 3 years ago. I always felt the low bass was very thin sounding. Any ideas? Thanks, Bob Sadowski Erie, PA
