If you want to read a full treatise on the subject, as usual Wikipedia is a good place to start. Their page is here. In short, it is a piece of music which starts with a melody sung in succession by each voice, in different keys. This leads to variants of the melody being sung in counterpoint, again in different keys, eventually the main tune coming in definitively in the original key before the whole piece comes to a conclusion.

Brahms is probably one of those composers.
