Begbie argues that western music has at times been too intellectualistic and denied to somatic necessity in music:
The elaboration of musical notation and of highly complex compositional techniques ‘has encouraged a focus on the structural rather than the kinematic properties of music'” (27).
This gives us a wonderful trinitarian necessity. That is, it gives us a logical necessity for the three persons as opposed to logics that necessitate only one or two.
God the father is the musician, the singer. God the Son is the Word and God the Spirit is the Breath that intones the Word. The Breath is necessary because the structure is not enough to ensure the structural coherence or delight in the music.
