Is there a rule in SATB writing regarding the Soprano & Bass moving in contrary motion?
Contrary Motion in SATB Writing: Exploring Independent Parts
In the realm of SATB (Soprano, Alto, Tenor, and Bass) writing, the movement of the Soprano and Bass voices in contrary motion is a topic of interest and consideration. While not a strict rule, it is generally advised to employ contrary motion in order to create independent and distinct melodic lines within the ensemble. This article delves into the significance of contrary motion in SATB part-writing and its role in achieving harmonic balance.
The Purpose of Contrary Motion
Contrary motion serves various purposes in SATB writing exercises. One primary objective is to avoid parallel fifths and octaves, which are generally considered undesirable in traditional harmony exercises. By incorporating contrary motion, composers and arrangers aim to create a more harmonically rich and sonically pleasing texture.
The SATB Writing Context
SATB writing refers to the four voices commonly found in choral settings: Soprano, Alto, Tenor, and Bass. Part-writing exercises in SATB focus on crafting individual melodic lines for each voice while considering their interaction and the resulting harmonic sonorities. Achieving independent movement and melodic interest in each voice is a fundamental goal.
Guidelines for Melodic Lines
When composing melodic lines in part-writing exercises, certain guidelines are followed to ensure singability and musicality. The melodies should primarily consist of stepwise motion, with occasional larger leaps balanced by stepwise motion in the opposite direction. This approach creates a smooth and flowing musical line that is pleasing to the ear.
Intervals such as tritones, sevenths, and intervals larger than an octave are generally avoided in melodic lines due to their difficulty in execution and potential disruption of the overall balance among the voices. Singability and cohesion among the voices are key considerations.
Tendency Tones and Melodic Resolution
Part-writing exercises take into account the concept of tendency tones. These are scale degrees 2, 4, 6, and 7, which have a natural tendency to resolve in specific ways. Composers and arrangers consider these tendencies when crafting melodic lines, ensuring that the melodic resolution sounds satisfying and musically meaningful.
Exploring Motion Types
In part-writing exercises, a variety of motion types can be employed to create interesting and independent interactions between the voices. Alongside contrary motion, other motion types include parallel motion, direct motion, and oblique motion. These different motion types allow for diverse musical textures and interactions within the ensemble.
Interval Progressions and Harmonic Considerations
Standard interval progressions form the backbone of part-writing exercises. Composers and arrangers rely on common harmonic progressions to create harmonically stable and pleasing passages. However, specific interval progressions, such as parallel unisons, fifths, and octaves, are generally avoided due to their potential for harmonic instability and lack of individual voice independence.
The Flexibility of Part-Writing Guidelines
The guidelines for part-writing exercises are based on the compositional practices of esteemed composers, including Johann Sebastian Bach. However, it is important to note that these guidelines are not rigid rules but rather serve as a foundation for learning and exploration. They allow for a degree of flexibility and creativity, enabling composers and arrangers to develop their own unique musical voices while maintaining harmonic coherence and individual voice independence.
