Abstract: The evolved delta Scuti variable 4 CVn was observed photometrically for 53 nights on three continents. We found a total of 34 significant and 1 probable simultaneously excited frequencies. Of these, 16 can be identified as linear combinations of other frequencies. All significant frequencies outside the 4.5 to 10 cd(-1) (52 to 116 mu Hz) range can be identified with frequency combinations, f(i) +/- f(j), of other modes with generally high amplitudes. There exists a number of closely spaced frequencies with separations of similar to 0.06 cd(-1). This cannot be explained in terms of amplitude variability.
