Hendecasyllables sound a bit like this:
eleven units, rhyming not required,
because ancient Greeks and Romans hated rhymes
and thought they were a bit stupid and contrived.
While iambs and spondees are acceptable,
dactyls and trochees are still preferable.
The stress patterns all have a title: Sapphic
such as this line, also the line above it.
Choriambic lines, also called Phalaecian,
offer different rhythms like this stanza.
Alfred Tennyson, Swinburne, Frost, Catullus,
and Trissino's Sophonisba use this style.
