  To produce sounds, we adjust the tension of our vocal folds to shape their
properties and control the pitch. This efficient mechanism offers inspiration
for designing reconfigurable materials and adaptable soft robots. However,
understanding how flexible structures respond to a significant static strain is
not straightforward. This complexity also limits the precision of medical
imaging when applied to tensioned organs like muscles, tendons, ligaments and
blood vessels among others. In this article, we experimentally and
theoretically explore the dynamics of a soft strip subject to a substantial
static extension, up to 180%. Our observations reveal a few intriguing effects,
such as the resilience of certain vibrational modes to a static deformation.
These observations are supported by a model based on the incremental
displacement theory. This has promising practical implications for
characterizing soft materials but also for scenarios where external actions can
be used to tune properties.
