sixteenth-dotted eighth rhythm in "Peace Like a River"

A few days ago I had you sight sing Peace Like a River.  The notation I included with the lesson had a mistake in the rhythm for the word "river."  I notated it as two eighth notes,  but the way I sing it is a sixteenth note followed by a dotted eighth note.  This is a new rhythm pattern and the first part of today's lesson introduces it briefly.  You'll also sing the chord progression for the song which uses only the I, IV and V chords for C major which are C, F and G (see explanation if needed). Part two of the lesson (tomorrow) will teach you three simple harmonies that you could sing following the notes in the chord progression.
