The Pure Drop
This is a common way of referring to a style of playing tunes. It doesn’t need to mean where the music originated; although there are plenty of Irish tunes played in a style which is considered "the pure drop".
The pure drop of Irish music is more how you do it, less about where it goes or even where it’s been.
I use the phrase not to have anyone call me a purist, which they will; rather because it’s the only way I have to put it into words. Do you know what I mean?
