Their band is mostly brass (aside from clarinets) which creates a more bombastic sound, they high step or whatever they call it for both pregame AND halftime
I think our band matches up relatively well with the rest of the Big Ten bands, and is way better than bands in most of the other conferences. The TCU folks certainly know our band is better than what they are used to seeing in the Big 12.
I have mixed feelings about the Wisconsin band. They put on an unusual show on the field and certainly make an impression, especially at Bowl games with fans that have never seen anything like them.
On the other hand their sound is sort of bad, even if loud, and unlike our band they have almost no presence during the game. Our band is always playing in the stands between plays and during dead spots. The Badger band is rarely heard on a TV broadcast, even after a TD, at least "On Wisconsin".
There are some bands in the Big Ten that are in the lower tier (of three) due to size or general mediocrity (Northwestern, Iowa, Indiana, Maryland, Rutgers), and 2 of 3 that are considered elite, but the Penn State, MSU, Minnesota, Michigan and Purdue bands are all very solid. The Iowa band used to be in this group, but is no longer.
Ohio State does have a very loud sound with small numbers, and Wisconsin is what it is. Illinois probably has the other elite band but get no credit. They are a very large band with a lot of brass that makes a good impression in person, and a very good sound. Penn State is somewhat similar.
The fact that our band has several good, school songs to play during pregame and in the stands helps relative to others that are lucky if they have two. (Iowa, Illinois, , Indiana Ohio State, Penn State (3). I know the other 8 schools have more than one school song, but most of them are very obscure.
