GENEVAN 81 was first published in the 1562 edition of the Genevan Psalter; Dale Grotenhuis (PHH 4) composed the harmonization in 1985. This bright tune in Ionian mode (major) has short phrases, two of which are repeated (AB, AC, CD), making it one of the simplest in the Genevan Psalter. For that reason, generations of Dutch children started their weekly school program of memorizing psalms with this one, beginning with the stanza that included "Open wide your mouth, surely I will fill it." The psalm should be sung with much energy, though the mood shifts between stanzas 5 and 6. The text suggests antiphonal performance: stanzas 1 and 2 to be sung by everyone, stanzas 3 through 7 by a solo voice or smaller group (possibly ending with a unison repeat of stanza 1 by all).
