If you only learn or teach one phoneme, make sure it's the most common English sound - the schwa.

Like us, you might already use songs in class, and find that your students enjoy them. But have you considered choosing songs specifically to work on pronunciation?

An advanced student of mine speaks both clearly and usually correctly, but can often sound over formal and at times stilted.

Teaching pronunciation used to involve little more than identifying and practising the sounds of which a language is composed, that is to say, its phonemes.
