Elgar dedicated Variation VII to Arthur Troyte Griffith (1864 - 1942), a member of an architectural firm based in Malvern operated by a brother of Basil Nevison. It is likely Elgar first met Arthur in 1897. Figure 16.1 documents how Ein feste Burg plays "through and over" Variation VII. This illustration is significant because Elgar claimed the covert Principal Theme must play 'through and over' the set of Variations. To satisfy this critical condition, it must be shown precisely how Ein feste Burg fits over each movement.
Figure 16.2 illustrates how Ein feste Burg was carefully mapped over Variation VII based on melodic interval mirroring and the principles of counterpoint. Melodic interval mirroring occurs when note intervals from Ein feste Burg are reflected in the variation over comparable or identical distances between notes. These notes do not necessarily appear in the melody line of the variation. The contrapuntal devices of similar and contrary motion were also considered in this analysis. Similar motion is when both voices move in the same direction, but not necessarily by the same degree. Contrary motion takes place when Ein feste Burg moves in the opposite direction than the variation, again not necessarily by the same interval. Similar motion is indicated by SM, and contrary motion by CM. For the purposes of this analysis, similar motion includes any instances of parallel motion, and contrary motion any instances of oblique motion. In some cases, the upper voice of the variation moves parallel with Ein feste Burg while the bass line moves in a contrary manner. An effective counterpoint typically employs a fairly balanced mix of contrary and similar motion, something clearly evident with this mapping.
In Figure 16.2 a melodic conjunction is represented by a diamond-shaped note head, and a harmonic conjunction by a triangle-shaped note head. A melodic conjunction is defined as any matching melody note between Ein feste Burg and the movement's melody line. A harmonic conjunction is defined as match between a melody note from the covert Principal Theme and any non-melodic note from the movement. Both melodic and harmonic conjunctions must sound together to be considered a match.
Table 16.1 summarizes 78 melodic conjunctions between Ein feste Burg and Troyte. A melodic conjunction is defined as a shared note between the two melody lines. Share melody notes are dispersed over 42 of 72 measures in Variation VII, or just over 58% of the time. Ein feste Burg does not play in 8 out of 72 measures, i.e., measures 210 - 213, 223 - 225, and 252. Measures in which the covert Theme was deemed active, shared melody notes are present in 42 of those 64 measures, or almost 66% of all active measures.
Table 16.2 breaks down melodic conjunctions between Ein feste Burg and Variation VII by note type. There are six shared melody note types (A, A flat, B, C, F and G) with frequencies ranging from 2 through 35.
Table 16.3 gives a complete breakdown of shared notes between Ein feste Burg and the piano reduction of Variation VII. The number of shared notes is indicated by measure number. There are 236 shared notes dispersed over 64 measures out 72 measures. Of those conjunctions, 75 are melodic and 161 are chordal. Ein feste Burg was deemed active in 64 measures, so 100% of active measures have shared notes. There are 8 shared note types (A, A-flat, B, C, D, E, F and G) with frequencies ranging from 4 (D and E) to 105 (G).
