What makes it different

  1. Real CymaScope imagery

    The images were created in the CymaScope laboratories in the UK by John Stuart Reid and James Stuart Reid of CymaScope Foundation Ltd. The app was conceived by acoustic-physics scientist John Stuart Reid and built by Appum Studios, the team behind 432 Player.

  2. Hear a note, see its shape

    Every key on the on-screen keyboard shows the CymaGlyph for that note.

  3. Your voice, made visible

    Microphone mode turns your voice or live music into moving CymaGlyphs as you sing or play.

  4. Compare tunings by eye

    Switch between 432Hz and 440Hz tuning and compare the imagery for the same note.
