I have tried all of the usual.  I filed the hammers.  A monitor feeds back sound to the pianist.  When I explained to the church directors that it is the "vigorous" style of playing that sometimes causes strings to break, the pianist resigned.  Things were OK for a while but now there is a young lady who is firing scuds at the congregation faster than I can get there to collect them, get them duplicated and replace them. She is quite upset and beside herself.  She refuses to believe that it is the *way* the piano is played that is causing this.  She claims that she has played the piano "all her life" and has never seen or even heard of this happening.  The piano has a string cover which she yanks out and throws in the corner.  She also says she has never played a piano with a "blanket" in it and just "couldn't" play with it in there.  I have firmly insisted that at this point, it is a matter of public safety and won't have any effect on the sound. I am thinking that these wound strings must have particularly high tension.    Does anyone know if this is so?  Over the years I have heard of other such instances that were cured by replacing the wound strings with a set of lighter gauged, "happy" strings.  It would seem to me that a lower tension would solve the problem but in reading the recent post about "replacement strings", I am confused.  Some of these strings have been breaking at the bass bridge termination point rather than the agraffe.  That seems very unusual to me. Should the manufacturer supply a new set of wound strings and if so, should they be a set designed for lower tension?  I presume that heavier gauged, higher tension strings provide a bigger, bolder sound.  What effect would lower tension have?  Just as a theoretical question, would tuning the instrument to a lower pitch, say 100 cents lower prevent this from happening (with the same gauge but a *new* set of strings)?  (I do not view this as an option, just a possibility that might work in some other circumstance).  (I also would not even consider altering the regulation to deliberately produce less power). It is also interesting to note that to date, only wound strings have broken, no plain wire. Bill Bremmer RPT Madison, Wisconsin </BLOCKQUOTE> A charismatic church we used to attend and who I still tune for monthly, has a Young Chang G-213. They have a history of broken strings, to the point that I have nearly restrung the upper 2 sections (at individual times). Even with new bass strings and Renner Blue hammers (which I did not replace),  they broke them. I did order a set of lower tension bass strings from Mapes and replaced broken strings as needed. They need to turn the volume of the monitor up so the pianist can hear the other instruments in the band as well as the piano. Other problems is that the older Young Changs have a history of breaking strings and it is not necessarily the scaling. I did some measuring and calculations and they did not seem out of line as far is tension, string breakage percentage, etc. In fact the treble (in the G-213)  has very low inharmonicity. One idea is to regulate the letoff wider so the hammer will not hit the strings at so much force. I have been told that these pianos have some design problems such as too thick of soundboard (Del, please comment here). As to whether or not it contributes to broken strings, I am not sure. The reality is that a spirit filled type church will encounter these problems and you will make a lot of money replacing strings. Other than replacing the piano this may be your only option unless they go totally electronic and you do not have to serviced the piano again.
