2. In guitar driven worship, the keyboard should use pads and strings so not to conflict with the rhythm of the guitar.
Depending on what God gives you, your band may be more guitar driven than keyboard driven. The instrument “driving” the band is the one that the lead worshiper usually plays. It’s also the instrument that starts most songs, and sets the rhythms that other instruments play to. If you’re blessed, you have a band that can be both guitar and keyboard driven, depending on the need of the song. Then you can add variety and depth to your worship music.
When the guitars are instrumentally “driving” the songs, the keyboard has to be played differently. This requires a keyboardist with sensitivity. They have to know when not to play notes in the left (bass) hand. They have to know when to switch pads so not to compete with the tone of the electric guitar. They have to know when to drop out altogether.
Humility is truly a wonderful contribution to a Worship Band.
So if the guitars are playing a heavily rhythmic strumming pattern, the keyboard should play something else and not try and copy the rhythm using a piano patch. Simple, single-note melodies work well in this setting. If the guitars are playing a flowing, eighth-note, finger-style pattern, the keyboard should play long, sustained notes/chords. If the guitars are playing palm muted, chunky riffs, the keyboard should find alternate voicings for the chords and look for countermelodies in the pockets between chord changes.
