I have yet to decide what is less appropriate in a church setting: an altered flannel-gram which depicts Peter using Zacchaeus as a surfboard over the storming Sea of Galilee, or the alien muzak emitted from an electronic keyboard. While the controversial drums contribute in the form of time keeping, the keyboard aides in the congregation's need for sounds whose names end in "from outer space". Innocents such as "Violin", "Bells", "Tin Whistle", "Clap", "Human Voice" can't escape this awkward suffix. Our church normally packs the stage with practically an orchestra of musicians who play real instruments, a jamboree of sorts with their warbles and squawks but very talented nonetheless. But there is always this poor musician huddled in the centre transfixed on the bells and whistles and switches and buttons of this precarious contraption attempting to contribute hymn-worthy spaceship sounds to the chorus. Of course, not all keyboards sound like Jules Verne playing a Martian harp. Some worship bands can really pull it off without a hint of cheese in the air. Even hardcore band Underoath subscribes to the use of keyboards, but only in eat-able bite-sized chunks. When is an appropriate time for "Moon Piano" or "Star Tambourine" sounds to infiltrate the church environment?
