listening for parts in Dona Nobis Pacem

Today I would like you to listen to "Dona Nobis Pacem".  I recorded this last night at Community Singers practice.  Listen for low voices and high voices.  Listen for three distinct melodies.  We sing through the song two times.  Can you hear differences between the two?  Does it sound like more voices are singing one part than another?  Can you find the tonic?  Each of the three parts ends on the tonic and two of them start on it.  Try to sing along.  Tomorrow's lesson will have notation.  I didn't put it on today's lesson because I wanted you to listen without the music first.  Listening for parts in music will help you be able to sing harmonies by ear.
