Divisi

In musical terminology, Divisi ("div.") is an instruction to divide a single section of instruments into multiple subsections of instruments.^[1] This usually applies to the violins of the string section in an orchestra, although violas, cellos, and double basses can also be divided.^[2] Typically, 4-part French Horn sections include divided sections if Horns 1/2 and/or 3/4 are not playing the same music ("a2"). Other brass instruments can also be divided but it is not as frequent as with the Horn section. Woodwinds - especially Flutes and Clarinets - also utilize "divisi" to divide music between parts and even between players of the same part.
