There's an analog in music to the notion of concurrency, which is the polyphonic melody -- a single melodic line that, by jumping between disparate registers, expresses the simultaneous sounding of two (abstract) voices moving against each other. Of course, this depends on the assumption that pitches can be implied even at times when they're not sounding, which intuitively seems to hold: see Bach's Cello Suites for a canonical example of this practice in action.
