Veering off into left field – to build a marimbula

factoid

This is a long way from xylophones and propane-tank drums, but I’ve really enjoyed building cajóns and – for the first time – a marimbula.

Quick demo and walkaround

The marimbula is a Caribbean instrument, descended from the African kalimba, and generally functions as a bass. As you’ll see in the video at the bottom of the post, I first experimented with a 6-key marimbula built onto the back of one of my cajons, just to figure out the basics of construction.

This one is a 16-key marimbula – which I’ve decided has about three too many bottom-end keys and perhaps one too many high-end keys, as the sound quality falls off quite a bit at the ends of its scale. Next, I might try building one like a piano keyboard (with two layers of keys in white and black) centered in the middle of this scale.

The tuning has been kinda challenging – I finally settled on D – but I’m tuning it slowly by ear because the digital tuning apps can’t handle all the overtones it puts out. Anyway, it’s a helluva lot of fun to play – particularly on a nice, resonant wood floor – because it’s easy to play, and the notes send vibrations through your butt and up your spine. I take great satisfaction in building instruments that create physical joy along with pleasant music.
