Organ
and Vocal Quartette "King of Kings" in Halleluja Chorus - Handel
The superphysical effects of the organ, differing quite naturally from those of the piano, tend to occupy the space surrounding the pipes, and rise vertically to produce massed forms which increase in size as the performance proceeds.
Arias create ribbons composed of connected note-forms, globular or wave-like; in the case of organ music this formation is determined by the stop, and varies in colour with the note, and in size with the dynamics.
