I had a Baldwin where it was actually the name plate in the top treble section. It was not cast as part of the plate but simply stuck there with double sided tape and as it worked loose was vibrating loudly, but only on certain notes. --Dave On 3/9/12 5:59 PM, Rebecca and John Silva wrote: > Hi, > > When playing a particular note on a piano I saw today (Baldwin L) a harsh vibration would sound. The vibration would only happen for a moment (1/4 second?) even while the note continued to sound, it was about 1/2 the volume of the note and only happened when playing hard. -- Dave Doremus, RPT Piano Tuning& Restoration 504-263-2923
