It would seem to me that the harmonic rhythm (the speed at which the chords change within the work) would be the most logical thing to measure. Other specifications such as "thickness" (a crude way of saying the number of voices playing at one time), tamber (so that electronic instruments could be distinguished from natural ones), and dissonance should all be considered. However I would be surprised if there were a way to complete this tast without gross inconsistency.
