The challenge with music is that it is highly personal. What may be one woman’s bliss may be another man’s hell. From a contemplative perspective, music distorts one’s ability to be present to the immediate sensations and movements of the breath and body –yoga asana as meditation.
I have a strong contemplative streak, and rarely teach or practice with music. When I do so, I choose ambient sounds that subtly inform the background. I also play music because it forces me out of my box a bit and brings some color to the austere parts of my personality.
