String Quartet No. 4 is a work in seven movements, composed as a reflection on the last seven words of Christ in the cross. These are the titles of the movements:
- Father, forgive them, for they do not know what they are doing.
- Truly I tell you, today you will be with me in Paradise.
- Woman, here is your son.
- My God, my God, why have you forsaken me?
- I am thirsty.
- It is finished.
- Father, into your hands I commend my spirit.
The work is based on four sonorities, which represent the pillars of the Passion and Death of Jesus: Sin, Suffering, Repentance, and the Vision of Paradise. Each one of these sonorities plays a different role in each movement, unifying all seven movements in one only structure, which creates the dramatic line of the work. String Quartet No. 4 could also be defined as an “Oratorio Without Words.”
