SATB a cappella or accompanied. Here are three different harmonizations of this lovely tune by Baroque composer Adam Drese. The first stanza is harmonized by Samuel Sebastian Wesley, the second by Richard Shephard, and the third by J.S. Bach. Just a lovely piece for an evening service.
Round me falls the night; Savior, be my Light:
Through the hours in darkness shrouded
Let me see Thy face unclouded;
Let Thy glory shine in this heart of mine.
Earthly work is done, earthly sounds are none;
Rest in sleep and silence seeking,
Let my hear Thee softly speaking;
In my spirit’s ear whisper “I am near.”
Blessèd heavenly Light, shining through earth’s night;
Voice, that oft of love hast told me;
Arms, so strong to clasp and hold me;
Thou Thy watch wilt keep, Savior, o’er my sleep.
