As we can see a Chorale setting can easily be made better or worse!
Knecht and Wedeburg are describing the following textures:
Homorhythmic with upper three voices in close position
Wide gap between bass and tenor
Older method, for beginners
Simple rhythms in opening position
Tenor is lower than in the close style
Harder because left hand and pedal are now independent
More active rhythm, still in open position
All voices may be ornamented, even the soprano
Bach’s chorales from the cantatas belong to this type
The “Full-voiced Style” appears in Example 5c, where, according to Knecht and Wiedeburg, parallel octaves and fifths are allowed (Knecht 1795–98, 3:76; Wiedeburg THEORY and PRACTICE Volume 42 (2017)36 1765–75, 2:293-94).
Usually parallel 5ths and 8ves are allowed in the middle voices if the outer voices move in good counterpoint
Avoid thirds in the left hand (too thick)
Single voice doubled in three or four octaves with pedal
Used in congregatio nal singing for variety
3.1: Ornamented bass & varied harm.
3.2: Ornamented A, T, and B
3.3: All voices ornamented (also chorale in soprano)
3.4: Contrapuntal, canonic, or fugal ornamentation
4.1a: Thick chordal texture; middle voices may have parallel 5ths and 8ves
4.1b: Variation: Hold chords half value, always sustaining the soprano
- 4.2: Five or six independent ornamented voices without parallels
*Five textures for realizing a figured-bass chorale from Knecht (1795–98, 3:20, 36, 82–107), Werner (1805, 1–9), and Wiedeburg (1765–75, 2:293–96
