SOUPIR is written as a programme in three parts, which plays with both the feeling of our inner pulse and time.

In this programme, the audience is invited to scrutinize firstly a rhythmic shift in demi-soupir (eighth rest), then the stretching of silences in soupir (quarter rest or sigh also in french), and finally the filling of a similar time with successive accelerations of the same repeated material in demi-pause (half rest).

The processes used tend to disrupt the performers' mutual listening and therefore reveal misinterpretations or differences in accuracy with the score.
