Etymology of 打ち合わせる


How come `打ち合わせる` means “to arrange a meeting” or “to agree on something”. I
clearly see the `合わせる` part signaling an agreement. Yet however I can’t see
where the `打つ` part became something other than “to hit”, “to strike”. Does
this verb has a canonical meaning that would together with `合わせる` clearly make
this non-physical meaning?

explains the etymology.

The term comes from court music, where wooden sticks were used to set rhythm
for all instruments. Originally, `打ち合わせ` referred to clapping (`打つ`) of those
sticks used to make the rhythm match (`合う`). The meaning then generalized and
the word is now used for preliminary discussions that ensure that all involved
parties are on the same page.
