Like much Hispanic folk music, NO HAY DIOS has simple harmonies. The melody is matched by a parallel line found alternately in the alto and tenor line. That parallel line, either the interval of a third or a sixth below the melody, makes for good duet possibilities (see. 1 and 3-soprano and tenor duet, see. 2 and 4-soprano and alto duet). Because the range of both tenor and alto is just an octave (from A to A), that harmony part would be accessible to either altos or tenors, who could switch back and forth from treble to bass clefs. Accompaniment is designed for piano, guitars, and some rhythm instruments, including maracas, castanets, and woodblocks. Try making up rhythmic patterns that reflect the joyful confidence of this song. Use a light registration if organ is the only available instrument. In the medley fashion typical of Hispanic performance, try pairing “There's No God as Great” with some of the eight other Hispanic songs in the Psalter Hymnal (234, 186, and 629 would work well).
