Deconstructing polyphonic texture

Just revisited Janet Cardiff’s website for  “THE FORTY PART MOTET | 2001″.

Even though I have not seen/heard this installation yet, I’m sure it must be awe-inspiring: a deconstruction of the polyphonic texture of Thomas Tallis’s Renaissance masterpiece Spem in Alium into its 40 individual voices.

I want to touch upon ‘The Forty Part Motet’ briefly , as its concept is related to the central concept of my current project ‘MULTIPLE voice/vision’ where I also envisage to deconstruct the polyphonic texture of music, but both aurally and visually. The first phase of ‘MULTIPLE voice/vision’ will centre around ‘Ein Musikalisches Opfer’ from Johann Sebastian Bach, which is a masterly demonstration of counterpoint.  ‘Ein Musikalisches Opfer’  was a musical gift - hence the titel - to Frederic the Great, King of Prussia. A gift consisting of contrapuntal elaborations on a musical theme devised by the king himself:

the Royal Theme

Ein Musikalisches Opfer - the Royal Theme | 1747

The first music sheet carries the inscription “Regis Iussu Cantio Et Reliqua Canonica Arte Resoluta” - “At the Kings’s Command, the Song and the Remainder Resolved with Canonic Art” -  the initials of which form the word RICERCAR, the older word for the musical form ‘fugue’. And as ‘ricercar’ also means “to search for”, the word is already indicative of the intricate puzzles and textures that Bach has woven into ‘Ein Musikalisches Opfer’.

single-point perspective exposed/imposed

Felice Varini is a Swiss painter obsessed with perspective. His canvas however is architectural space.

He explains in an interview:

I start my works from one vantage point, which is simply the height of my own eye level. This is only a starting point, a way to begin. I plan the work using sketches, pictures, camera, or just in my head. And I work with the space, considering the relationship of my view point with the space as well as the geometry of the space itself. Then I make the painting.

[...]

If [the viewer] is aware of the work, he might observe it from the vantage point and see the complete shape. But he might look from other points of views where he will not be able to understand the painting because the shapes will be fragmented and the work too abstract. Whichever way, that is ok with me.

Varini’s work is an interesting contemporary iteration of single-point perspective:

Instead of using single-point perspective to capture a 3 dimensional physical (or architectural) space on a 2 dimensional canvas, Felice Varini projects (from a single-point perspective) the content of a never painted 2D canvas onto a 3D physical space, where it is really painted.

The viewer sees broken, fragmented forms and shapes and lines superimposed on the architectural space. But from one vantage point all these fragmented lines and shapes coalesce into one geometrical form.

This clearly is a contemporary form of anamorphosis and reminiscent of  the technique used in e.g Emmanuel Maignan’s anamorphic fresco in the Monasterio of SS. Trinità dei Monti in Rome (1642).

visualization in 3D space

NOVA is a 3D led screen, developed by ETH Zurich.

It  has many possible application fields, and

is used for academic research in the area of human computer interaction for the development of 2D and 3D interfaces involving visual and haptic inputs and outputs.
