Final answer:
The constant use of the amen chord progression (i, iv, i) is an example of Harmony and Melody in music.
Step-by-step explanation:
The constant use of the amen chord progression (i, iv, i) is an example of Harmony and Melody in music.
Harmony refers to the combination of different musical notes played together and how they work together, creating chords and chord progressions. In this case, the i, iv, i progression represents the tonic (root) chord, followed by the subdominant (fourth) chord and then returning to the tonic chord. This progression is commonly used in many musical genres, including gospel and jazz.
Meanwhile, melody refers to the sequence of musical notes that are played one after another to create a memorable tune or theme. In the amen chord progression, the melody is created by the movement of the individual notes within each chord, as well as the movement between the chords in the progression.
