Mssr. Shea decided to expound upon the numerical significance of the number of fish caught gospel reading today, in which the number of fish is clearly identified as 153. If'n you wanna wade through his exegesis feel free to type in "patheos" in your search window.
I did share in common with him a moment of fascination about 153. However, as a lifelong musician and not too shabby theorist, what do you think was my Rorschach response?
Of course, scale degrees 1 (Tonic)- 5 (Dominant)- 3 (Mediant, whether major or minor.)
If that ain't Trinitarian, I dunno what is. You can do the existential math with either Greek or Baroque emotional associations.
One way or another, a tuned 1-5-3 is a totally beautiful thing, even if it stands alone.
