rythme non rétrogradable

Non-retrogradable rhythm — a rhythmic palindrome that reads the same forwards and backwards. Central to Messiaen's rhythmic language, inspired by ancient Greek and Hindu metres. The symmetry is felt as stasis or suspended time rather than metric drive.

Feel the internal symmetry of these rhythms rather than counting them as a simple sequence of beats. They expand outward from a central point. Practise by identifying the axis of symmetry and confirming that each duration mirrors its counterpart.
