Seventh in a series of "Idiosyncratic Tone-Pieces" for concert organ (the instrument ideally of the "French Symphonic" variety). As the title suggests, this prestissimo study in fragmentary melodicism and harmonic severity intends to evoke the ordered chaos and prideful turpitude of a Witches' Sabbath. Note the recurring, quasi-ostinato figure, transformed in pitch and rhythm in the second section, derived from the rather strange Double Harmonic Major mode with its characteristic two augmented sections and resultant cohemitonicism (successive adjacent semitones). The painting in the video is "Incantation" by Francisco Goya.
