Chalice Oscillate Metronome

I sing for you

In voices three

One for the moon

One for you

One for me

Your chalice filled with blood

And my heart, with wine

My aria ascends in 4/4 time

The metronome oscillates

Left

Right

Repeat

My vocal chords

Wither

In a show of defeat

Crescendo, suspend

Collapse to an end
