That’s a self-explanatory topic title: What instrument has come the furthest in today’s music and what instrument has fallen off course? By “today’s music,” let’s say the last 10 years. By “come the furthest” I mean which instrument’s role has expanded most significantly, or something along those lines. By “fallen off course” I mean which instrument’s role has diminished or been stunted the most. You can be a wiseacre and nominate the triangle or you can be the thought-provoking Townsperson we know you to be.
