Here is my entry for the march 2008 competition.
It is a baroque-style piece based on the principle of invertible counterpoint. It has 2 themes that can be combined upside down.
The first theme is developped through a passacaglia and appears as an ostinato. Seven variations on this theme are made, with the rythm increasing progressively.
The second theme is developped through a fugue. Since we have only 2 voices, various ranges of the instruments are used to emulate 4 entries of the subject. The fugue is of course a 2-voice one.
At the end of the fugue, to conclude the piece, the 2 themes join together for the final climax whilst the rythm is calmed down.
You will note that there is no dynamics indication in the score, on purpose. In the traditional baroque style, it is up to the performers to choose whichever dynamics they feel appropriate.
I have included a MIDI, a PDF and an MP3 realization of the piece. However, I use free software on Linux and therefore the MIDI does not contain the notes for the ornements (pralls, trills, etc...), as LilyPond (the notational software I use) does not generate them. You will find all the files
here.
Happy listening and judging.
