I asked Janice as nowadays she plays more than me. My Martin box is in a closet and my bass fiddle gathers dust in a corner. She tends to favor minor keys or keys that have a lot of minor chords. I’m sure our love of the blues plays a part in that. She kinda defines chords as happy or sad smile but a favorite key per se would be hard as she has a pretty good range and settles in on the key that both fits her range and the mood of the tune.
