Repetition is more common in non-Western music, and us Westerners can really get annoyed by it. One way to reduce repetition, especially if the melody is easily singable (as are most hymns and worship songs) is to make the song multilingual.
We have transcribed popular worship songs involving lyrics in Spanish, French, Portuguese, Tagalog, Gaelic, German, Swedish, Mandarin, Afrikaans, Romanian and Korean. If you need help obtaining a certain translation and/or chord chart of a song, let us know!
One great example of a bilingual duet is the execution of the popular song "Holy Spirit" in English and Spanish by Genessis & Nikki (pictured above).
