Bear in mind that there are plenty of airs that aren’t associated with any songs, they’re just pieces of music that are played slowly.
I appreciate airs from the sean nos tradition, but I honestly do not see why it would be such a big deal following such a piece of music with a tune. Now, of course, it would be different if the air was actually sung; a reel or jig after a “sung” air would seem a little out of place to me… just my 2 cents.
Don’t you think it would be a good idea to give a translation of the Bulgarian? It means ‘Slow Song’ or slow air – the equivalent of the topic of this thread.
