December is a time which invites reflection. That is true wherever you might be, and whatever else may be going on.
December can also be a time of many things to get done, holidays to celebrate, gatherings to attend, travel plans, resolutions for the coming year...
Each of those activities will benefit from a bit of space, a bit of time for reflection. That may come before, during, after you take part, of course—and music is a fine way to invite reflection and a fine companion alongside quiet consideration, as well.
