I'm sure j_menz will pitch in on this. Or out. In my humble opinion, metronomes are primarily useful for annoying students and friends; holding stacks of music down when the window is open on a windy day. and impressing visitors and in-laws... once in a long time I will use one, just for curiousity, to see just what tempo I am using anyway, an exercise which never ends well...
So.. what was that..
Or do you simply NOT use a metronome?
