Final answer:
The statement is false; in a fugue, the subject is stated first, and the countersubject comes in with subsequent entries.
Step-by-step explanation:
The statement is false. At the beginning of a fugue, the subject is stated first, usually in one voice. The countersubject, when present, is typically introduced in a subsequent entry of the fugue subject in another voice, counterpointing the main subject. The fugue commences with the exposition where the main theme or subject is presented and is then followed by entries of additional voices which might bring in the countersubject. Hence, the countersubject is not stated alone at the beginning; it is introduced after the subject has been presented.
