The title Seagha & Ground implies two parts, but it is two parts simultaneously are as one.
The use of the melody Seagha in a fugue where the melody is alternating between the use of the harmonic row of each rotation of Seagha. Each time the harmonic row is presented another tone is added to the melody going from two tones to all six. Each time the overall melody completes and the tempo changes, one less harmonic tone row is used, eliminating the shortest row (2 tone through 6 first, then 3 tone to 6, 4 tone to 6 etc.).
The concept of ground is sort of like a cannon, but it is simply the repetition of a base line; which of course is Seagha.
