Spiegel im Spiegel

0:00-0:34 Bell and first line

  • Piano places the repeating bell tone before the violin enters.
  • The structure starts as a rule, not a theme: still point, step, return.

0:34-2:18 Mirrored ascent

  • Violin rises by patient degrees while the piano keeps the reflective grid.
  • Each phrase feels new only because the same shape has moved slightly higher.

2:18-5:08 Expansion without release

  • The piece widens by extension rather than contrast.
  • No new section breaks the spell; duration itself becomes the development.

5:08-6:35 Suspended close

  • The final passes narrow the distance between motion and stillness.
  • The ending does not resolve the mirror. It stops while the rule is still audible.
