Can "listening" be countable?

Can listening be countable? Can I say We will do a listening during today's lesson?

Solution 1:

You can treat pretty much any -ing word as countable if you want to. Whether you want to or not depends on the effect you’re striving for. There is, for example, a children’s rhyme which includes ‘We / Are tired of scoldings and sendings to bed: / Now the grown-ups shall be punished instead.’ In other contexts, sendings would sound strange, and listenings would normally sound strange to me, too. Best avoided, I'd say.

Solution 2:

It might raise some eyebrows, but I don't believe it is wrong.

A Google Books search for "Some listenings" yields plenty of results.

By analogy, a viewing (of a house, or a movie) is countable.

There will be a viewing of my new movie on Thursday.

There will be a listening of our new record on Thursday.

Unusual, but not wrong.
