The biggest problem with congregations is they appreciate music but know little about. Being heard "some of the time" will get a better reaction than being heard all the time. Some hymns I will lurk in the undertones of the song and then others I will bring it out a little more. Also, everyone will complain about bad music without knowing what to complain about. Most times for brass players its the volume but bad tone and wrong notes will get you the attention you are not looking for. Once there was a choir member who complained I was too loud. His reply was for the choir to sing louder. Was glad for the support but at the same time he knew I would bring it down a little. Volume is the key to getting along in church music. The best advice for those in church orchestra is this, you will be frustrated a lot, but taking the high road will always bring you more satisfaction than pitching a fit and blowing up. Then again, if it is that bad, then attend a church where you fit in more so than appreciated for your talent. For me I play to Glorify God first and foremeost. Second on the list to allow people to get to a worshipful state through the music being played. I never perform in church but at the same time you want to play as well as you can so others can experience the same.
