The sequence of tenses in German is rarely dealt with in a systematic fashion, by occasion in the chapter Consecutio temporum, or sometimes Tempuskongruenz. Obviously it is by no means a major axis in the study of tenses, which could be interpreted as a specific feature of the German grammatical discourse. No doubt in German a number of constraints, both systemic and contextual, carry incidence over selections of temporal forms in complex structures. Those constraints are of course observed by grammarians or linguists, which implies that they resort to other types of explanation. But this relative silence may be motivated by some reasons, among which the general tendency to discordance rather than concordance when it comes to verbal systematic relations in complex sentences, or textual structures. The purpose of this study will therefore be first to pick out and list the “constellations” which we can interpret in terms of sequence of tenses, and then those where no concordance relation is to be found, and which can be defined in terms of discordance. But we will also have to account for the absence (or just about) of that question in the linguistics literature about the German language.
