It turns out that sound behaves like both wave and particle much as light does:
Researchers have gained control of the elusive “particle” of sound, the phonon. Although phonons — the smallest units of the vibrational energy that makes up sound waves — are not matter, they can be considered particles the way photons are particles of light. Photons commonly store information in prototype quantum computers, which aim to harness quantum effects to achieve unprecedented processing power. Using sound instead may have advantages, although it would require manipulating phonons on very fine scales.
In other words, waves and particles behave the same way, suggesting that pattern is more important than form, and that this patterning communicates information which serves to store and forward energy. Sounds about like most of my listening experiences.
