The slowing down of a recording or live performance of a piece of music to enhance its therapeutic impact. The precise amount of the slow down is essential for the effect to work, and it varies from style to style and with other circumstances. The term is Diamond’s coinage, from German prefix ur-, original (as in Urtext, for example), and tempo, speed.

Timeline: 2013 on.

Commentary: Urtempo is one example of Diamond’s ongoing work to increase the Life Energy of music in performance and recordings.
