Johannes G. Bastiaans (PHH 418) composed ONTWAAK (awake) in 1866 for the original Dutch text. The tune was one of thirty that Bastiaans provided for the Vervolgbundel op de Evangelische Gezangen (1868) after being commissioned to do so by the Nederlandse Hervormde Kerk. ONTWAAK is also one of several of Bastiaans's tunes that remain popular to this day in the Dutch Reformed churches.
The tune is a bar form (AAB), a rarity in Bastiaans's tunes. Its melodic contour consists of a delicate balance of larger intervals and stepwise motion. Sing either in unison or in harmony. A more dramatic rendition might involve soloists singing stanzas 1-3 and the entire group singing stanza 4.
