Will your congregation actually sing this?
Tell Singable a song's range and where the melody sits. It scores how hard the song is for an average congregation to sing — by vocal range, tessitura, and strain across low voices, high voices, adults and children — names the friendliest key, and returns a short pastoral read of the result. It reasons from established vocal-range norms; the comfort thresholds are a tunable judgment layer, not hard population statistics.

Singable measures the performance — range, tessitura, key fit, and who strains. It can't see why else a room might not lean in: an unfamiliar or strange melody, dense or hard-to-grasp lyrics, language, instrumentation, or simple newness. Those are hypotheses, not measurements — and lyrical depth is Clear Worship's job. A future "didn't sing with us" journal will help you log songs that fell flat and weigh these causes.
