Fugue with 3 themes, 4 voices, 4/4 beat, discontinued at bar 239
A fugue with three themes. This piece is the only one not including the
common theme of the art of fuguebut having three brand-new themes.
In Cp.8 and Cp.11 with three themes, the structures of both are rather
complex that before all themes were finally combined, there haｄ been an
insertion of already exposed theme or re-exposition of combined themes,
yet, in this piece, the process is simpler that once used theme is combined
after the theme was exposed, and this order is repeated until three-theme
combination.
Three sections make up of the piece, clearly divided by cadenza.
