Hi Mg
Thanks for the in depth analysis of this little tune .It is indeed a nice easy peace to play along the bass line in C ,whatever the intention of the composer.

quote:I don't see any inescapable logic to the key signature, and wonder if perhaps it was assigned to reduce the number of accidentals to a minimum, which would make sense.

We call it " artist´s freedom " in EU.
Thanks again and regards
