+The '''virtual fundamental''' (VF) or '''virtual pitch''' is the perceived [[pitch]] of a missing fundamental frequency when only its [[harmonic]]s are present.
+This phenomenon allows the brain to create a perception of the fundamental frequency even when it's not physically present.
+The concept can also be applied to chords. This is the easiest to see when a chord is written as a sequence of overtones.
+For example, the virtual fundamental of a [[4:5:6]] major triad is the fundamental: '''1''':4:5:6, which in this case is two octaves below the root of the triad.
+The virtual fundamental may be found similarly for tempered chords, if there is a clear just interpretation.
+However, in the general case, the virtual fundamental is often ambiguous or not well-defined at all.
