The instrument that is typically associated with marches is the brass band, particularly featuring instruments like the trumpet, trombone, and tuba. These instruments provide the bold and powerful sound that is characteristic of marching music. Additionally, the snare drum and bass drum play crucial roles in maintaining the rhythmic backbone of the march. Marches are often composed for military parades, sporting events, and other celebrations, where the combination of brass and percussion creates a lively and engaging atmosphere that encourages movement, which is why they are prevalent in such events.
