Mitblasen
Mitblasen is a German verb formed from mit- (with) and blasen (to blow). The core sense is to participate in blowing as part of a wind instrument or in a group that is producing sound. In musical contexts, a player may “mitblasen” when joining an ensemble or accompanying others, for example by blowing a note along with the group. Grammatically, mitblasen is a separable verb: in the present tense you say “ich blase mit,” “du bläst mit,” “er bläst mit.” The past participle is “mitgeblasen,” as in “Er hat mitgeblasen.”
Beyond the literal sense, mitblasen is also used figuratively in colloquial speech to mean to go along
Etymology and usage notes: the prefix mit- indicates accompaniment or participation, and blasen provides the act
