I've been on a music tour bus for more than four weeks playing Christmas music with pianist Lorie Line. Someday, I'll post her music but it is now Epiphany, and I am in a self-reflective mood and this music suits me.
This particular composition by Pärt steadies my breathing at first and like Samuel Barber's Adagio for Strings raises my temperature ever so slowly until I find that there is a pounding in my chest.
Pärt's compositions mirror one's meditation on resounding bells, tintinnabullations. This music centers around the focus you bring to the listening experience. If you've never heard it, do yourself a favor -- pause...calm your mind and body...close your eyes...concentrate your breathing...focus on your heart beating...and you will be rewarded.
