About the piece

This is essentially a piece on beats. It is an experiment with repeating 16ths, eventually climbing scales also become part of the equation.


The title is from the book of revelation, and relates to the feeling of rapture spoken of in the text. In other genres, and also traditionally music that has a loud bass, accelerating rhythms like in this piece is often used to produce feelings of ecstasy. "I heard behind me..." plays with the same mechanisms, but in a slightly different way.


It is also a piece about nagging. In fact the first title for this piece was "Nagging". The nagging aspect is used in a more general sense, meaning that it might be annoying with repeats, like it is with children going on about stuff they want, but i find it very interesting that in music, the same rules don't apply. What would normally become nagging, turns into something else. Stylistically something also happens to the music when it is repeated. It starts morphing into other unexpected forms.

Technical information:

To play the computer part, the patch for MAX/MSP is needed from the composer.

It is not self-sufficient, and will need a player through the performance to operate it.


One will also need a computer capable of running the MAX/MSP runtime environment.

The patch is only tested on Apple computers, and will run nicely on a G4 867MHz.

A soundcard with one in and two out is also needed. It has to be set to very low latency.


Other equipment:

A PA-system with two smaller speakers (Genelec 1029 or equivalent) to be placed as close to the soloist as possible.

A microphone for the singer connected to the soundcard
