Playing Chords on fiddle at sessions
So, a few days ago I was at session with my fiddle, playing the tunes I knew, and sitting out the ones that I didn’t, and then a tune got played, that I didn’t know and it was in D major. Having tried mandolin for a few weeks, I knew a little bit about chords and what sorts of rhythm to play, but the only chord patterns that I know on mandolin only really work with tunes in D. So I thought that seen as it was a reel in D, I could play some chords to it on my fiddle.
I sat out the tune for the first time, so that I could get a feel for the rhythm and what have you, but then I joined in (strumming) some chords on my fiddle. But about 20 seconds in, the session leader started glaring at me and only stopped when I was quiet.
I’m wondering what the session leader could have against me strumming out a couple of chords (quite quietly as well) on my fiddle, and if it would be OK in other sessions?
