What Makes a Great Music Arrangement?

A question often asked is – what makes a great music arrangementrefers to the structure and order of musical elements in a composition, such as melody, harmony, rhythm, and instrumentation.?

It’s great if it’s written with the lyric and against the melodyA sequence of single pitches perceived as a unit, usually the main theme or tune in a piece of music. (has oppositional countermelodies), and organic reharmonization of the original chords.

“With the lyric” means the feeling of the accompaniment should reinforce the meaning of the lyric. Accompaniment is feeling, while the vocal line is a blend of meaning and feeling. It’s easy for an arranger to get wrapped up in the musical devices he’s exploring while forgetting the meaning of the lyric at any particular point of the song. Great arrangers always consider the lyric, and reinforce its meaning with their choices.

“Against the melody”  can mean:

• The countermelodyAn element of an arrangement adding a sense of commentary and completion in complement to a melody can happen in the holes in the phrasing. Every vocal line has resting points because the singer needs to breathe and songs are written with that in mind. A good countermelody might occupy those spaces, offering connecting material leading to the next phrase. These events could be as short as a couple of beats at the end of a barA line that separates measures in sheet music., or two bars worth of transitional material leading to the next section of the song.
• The melody occurs around notes that can be described as the “primary colors” of the harmony1. The result of notes sounding together to create a sense of musical logic or agreement 2. Supporting musical material 3. A sense of musical environment, another way of saying “chordTwo or more notes played simultaneously; a group of three or more notes played or sung at the same time to create harmony. tones.” There are two or three primary colors in every harmonic instance, beside the root of the chord which is assumed to be in the bass. A good arranger will write his countermelodies by ornamenting the other primary color, unused by the vocal line at that moment. There are exceptions. If the countermelody echoes the vocal line, it will use the same tones, rhythmically displaced. If the vocal line passes through all the primary colors, the countermelody might be written against the landing point of the melodic line.
• Another formThe structure or organization of a piece of music, including its sections, repetitions, and overall shape. of countermelody can exist in a different rhythmic density than the melody. If the melody is active, the countermelody can be static, and vise-versa. This might be a secondary countermelody, introduced after the first.
• The countermelody can oppose and resolve to the melody at times. This device heightens the tensionTemporary music dissonance or increased density and challenges the vocalist, but can produce very satisfying resolutions.

Organic Reharmonization means the chords used or implied by the arranger are derived from the functional scheme of the original harmony. Chords derived from a tonal system have a function within that scheme, most simply described as “home” and “away.” The tonic (or “I”) chord is “home,” and anything else is “away.” The primary ‘away’ functions are subdominant (“IV”) or dominant (“V”), each of which can be expressed by a variety of substitutions. Chords can be varied in countless ways through the use of diatonic substitutions, neighbor chords, interjected dominants, passing chords, and other devices. Some arrangers might discover a different functional scheme that they like for a song, but if they use it in the arrangement, they’re re-composing the song, and the reharmonization is no longer organic, violating the composer’s intent.

One common device that great arrangers use is the superimposition of a progression over a region of static function in the original song, increasing the density of harmonic events, which is an accepted and commonly used technique. The savvy arranger will do it while respecting the functionality contained within the source phrase of the original material.
