keys, but there are marches with introductions in minor keys, including "Gladiator", "The Picadore", "Nobles of the Mystic Shrine", and "Rolling Thunder". The next section is commonly called the first strain, as it is the first prominent melody of the march. The first strain is typically 8 or 16 bars long with 4-measure phrases. The first strain can be in either major or minor mode and can use any variety of dynamics, instrumentation and modulations. Typically this strain utilizes similar motifs (as opposed to contrasting motifs—see trio, below) in its phrasing, and it sounds more rhythmically straightforward than the following section. After the first playing of the strain, it is repeated once, sometimes with added parts such as counter-melodies. The first strain may be repeated yet again after the second strains, particularly if it (first strain) is in minor. Karl L. King frequently arranged this style, as did Henry Fillmore with his trombone smears. Examples include "Peacemaker March", "New York Hippodrome", "Caravan Club March", "Trombone King", "Lassus Trombone", "Royal Decree", and Price's "March of Youth". The second strain is usually 16 bars long and is the second primary melody of the march. However, in marches like "Solid Men to the Front", and Sousa's Untitled March, the second strain is 32 bars in length. Some marches commonly play the first run of the second strain quietly and the second run loudly; these include: "The Stars and Stripes Forever", "His Honor", "The Washington Post", "Hands Across the Sea", "On the Mall", and others, particularly by Sousa. The second strain may use somewhat different instrumentation or may alter the relative dynamics of the different parts. The melody is normally played with the basses, i.e., the low brass and low woodwinds). This strain typically uses 4-measure phrases, but with greatly varied motifs, which causes the melodies to sound more "stretched out". For example, many marches use more whole notes in the second strain than the first—as can be heard in "The Stars and Stripes Forever". Like the first, the second strain is usually repeated once, sometimes twice; but some marches, including "Emblem of Freedom", "Cyrus the Great" and the "Melody Shop", omit this repeat. The trio and repeats In some marches, a short introduction to the trio is heard, often a repeat of the opening introduction, or it may be a different melody played by the whole band, a fanfare by the brasses—or a
