Which of the following is not typical of medieval music? monophonic or polyphonic often not written down religious in nature mainly instrumental

The Answer is Mainly instrumental

Explanation:

Medieval music was also primarily vocal. Few instruments were used, and it was a long time before instrumental accompaniment was added to music. This probably stemmed from the fact that instruments were not allowed in religious services of the church. The majority of Medieval music was therefore written to be sung.
