Consecutive fifths

In music, consecutive fifths, or parallel fifths, are progressions in which the interval of a perfect fifth is followed by a different perfect fifth between the same two musical parts (or voices): for example, from C to D in one part along with G to A in a higher part. Octave displacement is irrelevant to this aspect of musical grammar; for example, parallel twelfths (i.e. an octave plus a fifth) are equivalent to parallel fifths. A common theory is that the presence of the 3rd harmonic of the harmonic series influenced the creation of the prohibition.
