Heh. My piano teacher recommended I get a metronome (I used to own one years back, for my clarinet practice, but I must have given it away because I couldn't find it up at my parents' house). So I decided to order one from Amazon.

(I really, really wanted one of the old fashioned ones, with the pendulum arm that goes back and forth, but those were twice as expensive as the digital ones and had fewer features, so I went with a little simple Korg digital model).

You know how Amazon suggests "companion items" - things that other people bought when they bought the item you did? Among the items that other people bought along with the metronome, was a set of the Hanon exercises.

Which is exactly why she told me to get the metronome (she wants me both to watch my tempo - like the horse that trots faster when it can see its home barn, I tend to speed up as I get close to the end of a piece, and because she wants me to work on playing faster (weep!))
