Virtutes Occultae by Taylor Brook

Virtutues Occultae is an album in eighteen sections for six physically modeled virtual pianos, each with a unique tuning in an extended 11-limit just intonation.

In writing this music I used a mixture of traditional composition methods of structuring the music with various harmonies and progressions along with more free writing, collage techniques, and algorithmic composition.

The tuning of the virtual pianos extends Harry Partch’s conception of the over-tonality.

This album also exists as a six-channel surround sound concert/installation format.
