Narrative:
Ground control on 121.8 instructed us to taxi via taxiway K, taxiway eg, and monitor ground 121.65. Instead of monitoring ground 121.65, prematurely switched to tower 126.55. After noticing this, switched back to 121.65 and asked if they had tried to call. They responded 'no, however, follow aircraft in front and switch to tower.' no conflicts. Concerned because tower and ground frequencys are similar.
