Thanks for starting this, SOP. I'm very interested in if and how other singers improvise.

I don't think I do - I do sing a song differently each time (expression, rhythm, varying line length, etc), depending on how I'm feeling and what I connect with in the song itself that day - but is that improvisation? as I don't think I depart from the basic raw notes in my head. (I don't yet have the courage!)

But I've been thinking a lot recently about improvising and experimenting more, to try new ways of singing the songs, so am keen to hear what other singers think/do.
