The Grace Kelly challenge on TikTok involved users harmonizing to the hit 2007 Mika song using multilayered tracking to overlap their vocal lines one on top of the other, moving up the scale until the final, high notes which complete the exercise. This collection from Pop maestro Roger Emerson imagines nine more of these challenges with certified bangers, arranged in 3 to 8 parts for your choir! The Performance Kit includes 10 collections along with free access to the ChoralMix lessons for each song online (sharable with all members of the choir) for a complete digital interface with separate vocal lines for learning!
