After all the heaviness Brahms opts for a short intermezzo marked
andantino for his dance movement in the
Quintet for Clarinet and Strings in B minor, Op. 115.
Andantino is used a lot by Schubert, but few other composers use it. Here it signifies a reasonable walking pace.
It has a sunny beginning in D Major, but at 1:40 the clouds return for a pensive middle section marked presto. At 4:16 the opening section returns in truncated form for a quiet and peaceful end.
