Choosing a key is a tricky business in this world of corporate sung worship. Trying to land on a key that allows men and women, young and old, competent and tone-deaf to sing out their praise to the Lord is nearly impossible. Like many things, you can likely find resources online that coach you through the key-to-key range that is best suited for congregational singing, but I am not a theory teacher, and this is not that post. Rather in this post, I want to offer a few points to consider when it comes to choosing a key:
What is comfortable for your range? Who is going to be leading this song? If something is out of range (low or high) for the vocalist who will be leading the song, it will automatically become more difficult for the congregation to follow along.
The original key. Many worship songs these days end up on the radio, which means they are likely pitched higher than even the worship artist would play or lead them live. Just because you can sing something in the original key doesn’t mean you have to. That being said, sometimes putting something in the original key can make it a lot easier for musicians and vocalists to learn their parts.
What else are you playing? A larger consideration for me in choosing a key to a song is the other songs surrounding it in the setlist. Now, this is not something I have to worry about as much using tracks and pads to smooth transitions, but I want to be able to move seamlessly from one song to another. As a guitar player this means thinking about things like - will I need to change a capo? Retune my guitar? If it is not in the exact same key, what are the transition chords I need to play to move me into the next song?
What key will be on the edge? Where can I pitch this song to encourage people to be right on the edge, and have to really sing out, but still be singable enough that they simply stop singing because it feels completely out of reach. I think about this with lighting in the worship gathering as well - I want it to be bright enough that people can see one another, but dark enough that they don’t feel exposed in their worship.
Consider the song. People will often give modern songs a hard time about the anthemic octave jump from one part to the next, but truthfully, if you sing a lot of hymns, the melody range can be just as significant. The only difference is that we have become familiar with these melodies in such a way we do not notice the jumps.
Ultimately, there is trial and error involved. One of the reasons I like Co-Leading, especially with men and women on the team, is that you can choose keys for a man to lead that will be comfortable for men, and choose keys for a woman to lead that will be comfortable for women. We need to be willing to serve our congregations, serve the song, and be willing to sacrifice some artistry - just because you can sing that high doesn’t mean this is the right place to make that known.
