Musicality
Circus marches are faster than a normal military march, often 130 to 150 beats/minute.
Although screamers tend to follow the march form, many times they are abbreviated, and additions, such as a quick cornet call introduction to a new melody, are included. The average screamer can last a minute to three and a half minutes.
Screamers are a very demanding type of music, due to their extremely fast and advanced rhythms, especially the low-brass parts. Double and even triple tonguing is often required in order to play these rhythms. The trio in The Melody Shop is a good example of this.
Many screamers have two prominent melodies playing at once. Although this is not unusual in a march, screamers tend to go further with this. The low-brass section can be playing a long, stately melody, while the woodwinds can be moving along with a phrase of 16th notes, or vice versa.
Due to the circumstances in which screamers are played, dynamics tend to stay at a level forte. Unlike some military marches, piano is rarely used.
