“Moments of silence are part of the music” is a saying that has been printed on several gift items. Robert Fulghum’s Words I Wish I Wrote: A Collection of Writing That Inspired My Ideas (1997) credited “Unknown.”
 
The authorship of the modern saying remains anonymous. It’s possible that the saying began on a wall plaque.

“On another wall we stencilled a quote, ‘Moments of silence are part of the music.’ I have no idea where it comes from, but we just like it because it spoke to us.”
