Montage Methods by Eisenstein

We do tend to measure "film" for as long as the physical film is. Musical metaphors are similarly to film metaphors too. So when we talk about montage in music we could be thinking about montage the same way in film.
In the different rhythmic structures of music, there are different levels. Eisenstein was really comparing music with film and editing..

In montage, when the image changes, you feel a beat.... kind of like in music. However in narrative film making you do not want the audience to feel the beat. In metric montage the cut is everything, and that is the most important thing.
