Prelude and Fugue in A minor - (2011)
nine-beat (4/4 + 5/4) ground bass as theme repeats, voices and other
development added as successive statements pass. The generally closed form
of the parallel triads is a part of the ground bass texture, setting it
apart from the additional lines.
top voice of the ground bass' triads becomes the fugue subject with some
octave displacement, twice repeated and rising a twelfth. Among the
episodes, at measure 21, the ground bass harmonies blur in octave
juxtaposition. With as much chromaticism as the theme offers, the statements
of the subject appear in only the tonic and dominant.
