Thank you, owlman5, for your reply.I suggest that you use "the guitar" in that sentence. "I was playing a song on guitar" sounds incomplete and a little off to me.
Thank you for joining the thread. So, my sentence is correct from a BE point of view (?)I agree, from a BE viewpoint, in this context.
We do often see "accompanied by Blahsy Bloggs on piano and Thingy Jig on drums", and so on, but that is a different context.
This use would fit with my BE idea of when to use the article.I was playing the guitar a few minutes ago.
I see. Thanks again.Your #4 crossed with my #5.

That's what I expected. Thank you for your reply.In AE, 'the' is more common with the names of musical instruments, too.
