End-of-term concert for Adrian’s percussion class. An eclectic mixture of Christmas music, pop songs, and made-for-drums creations.

Here’s Adrian expertly playing the marimba.

One of the pieces they played was “Crazy frog” which in its original version is known primarily for how annoying it is. Played by a percussion ensemble with several marimbas, xylophones and vibraphones in the foreground, it was surprisingly pleasant.

The photo is from their final practise run just before the concert. During the concert itself, the lighting was all weird and not at all photo-friendly: red and patchy. Some kids were squinting from having strong lights straight aimed in their faces; others were in total shadow.

After the concert, I tried to figure out what makes the marimba different from the xylophone. I asked a teacher but only got a mostly useless answer. (Yes, I heard that they have different sounds; yes, I can see that the marimba has a wider range.)

I did some reading when I got home and learned that one key difference is how they are tuned (to a different set of overtones) and how the tone plates are shaped. They look like flat pieces of wood at first glance but absolutely aren’t – they’re scooped out underneath into an arch shape, and that’s what changes the pitch. Yamaha has interesting articles about the tuning of marimba tone plates, among others.

The length of the resonators, the different types of mallets used, and the playing technique, all reinforce their characteristic sounds: deep and mellow for the marimba, sharp and bright for the xylophone.
