"Lament for John Roy Harris" was written by two local fiddlers, Don Fletcher and Denis Lanctot. To my ear, it has a Celtic flavour about it. But, the accompaniment style is called "Bach 1 Classical Piano - Classical Solo Piano Accompaniment. (Prelude 1) Arpeggios." I believe another local fiddler, Alf Warnock thought of using that style. I'm fascinated that you can mix Celtic and Classical styles and it ends up sounding so good - and that a computer can generate it just from chord progressions. I'll be trying more of this in subsequent videos.

Enough lamenting, here's the video.
