To further generalize, one could consider chords where differences between frequency deltas ('''precession''') are commensurable, while deltas themselves may not be. This corresponds to chords where differences between interference | To further generalize, one could consider chords where differences between frequency deltas ('''precession''') are commensurable, while deltas themselves may not be. This corresponds to chords where differences between various interference beatings go in and out of sync in a regular manner. One example would be a +(sqrt(2) − 1) +sqrt(2) +(sqrt(2) + 1) chord. | ||

* [[Linear chord]] - With linear chords, all the frequency differences between adjacent notes are simply related (i.e. equal or in a simple ratio like 1:2). With DR chords, some of them are, but not necessarily all of them. | * [[Linear chord]] - With linear chords, all the frequency differences between adjacent notes are simply related (i.e. equal or in a simple ratio like 1:2).
