One thing I miss about church in my old home town is the Advent hymns we always sang.
My favourite was O Come, O come, Emmanuel. It's been a couple of years since I've had the opportunity to sing this.
The song is a hymn sung for over a thousand years, originally sung in the Medieval era by nuns and monks or so I believe.
In this version here, the verses are sung in a variety of ways.
The first verse is Homophonic- meaning the melody is accompanied by block chords that mainly fit with the main melody.
The second verse is technically sung in polyphony with a few moments of monophony- the melody is sung in a sort of canon between men and women with moments where the voices unite at the same time.
The third verse features female voices accompanied by a solo oboe in a counter melody.
The fourth verse is again a polyphonic texture with men and women in a quasi-canon and unison moments.
The final verse unites the voices, organ and oboe - voices in unison with chords and the oboe countermelody.
I love the way the final chord is a Tierce da Picadie meaning that the song was in a minor key (sounds sad) but the final chord raises the middle note of the chord a semitone (half step) higher so it becomes major, sounding happy!
