“Compose a choral piece (SATB) suitable as a prayer in a religious service.”
You could use words if you prefer. Note the numbered bass and try and include harmonic movement, e.g. in the example – tonality in Bb (sub-dominant/IV – bar 3, and super tonic/ii – bars 6–7). Also in the example, there are two 64 chords on the tonic, including a passing chord, in bar 5 and a cadence chord in bar 7
Here are links to examples you could listen to before beginning work on your own original piece:
The last example is a recording by Stuart Burrows of the hymn, Rho im yr Hedd. This time, Burrows sings the highest line of the hymn-tune, which is the soprano part. The alto, tenor and bass parts are played by the accompanying organ.
Make notes describing what you hear in the above examples.
