As I mentioned in previous posts, MusiCamp was considering the possibility of campers making washtub basses as well as diddley bos this summer. So, this past Victoria Day my partner and I attempted to make a washtub bass.
For those of you who don’t know, a washtub bass is a one-stringed bass made up of a stick, a string, and an overturned washtub as the resonator (or better understood as what amplifies the sound of the plucked string).
We tried two different containers (the resonator of the instrument), two different strings, and a variety of playing techniques. While we quickly resolved what physical equipment (resonator and string) worked best, the playing techniques is clearly a work in progress ;) .
One container was a food-industry size oil container. It was metal and so I figured it would resonate more like a traditional washtub than the other alternative resonator, the 5 gallon plastic bucket. But the plastic bucket had a way fuller sound and the one we much preferred.
The two strings we tried was a cotton rope and a plastic weed-wacker line. We liked the rope more but it busted before we even got a chance to properly savour the sound. Luckily, the sound of the weed-waker line wasn’t dramatically different from the rope.
The construction simply involved taking a rake or broom handle, indenting a groove on one end and drilling a hole in the other. We also drilled a whole in the middle of the container/resonator. We then tied the one end of the weed-waker line to the container/resonator and the other end to the stick (which involved wrapping it around the stick a number of times and then securing it with duck-taped). Then we inserted the groove/indent on the rim of the bucket, the string becomes taught, and we started to twang away.
I had assumed that playing different pitches/notes involved moving the stick back and forth; however, this seemed very difficult to keep in tune -as you can see in the youtube video below.
The playing technique that I soon adopted involved placing the stick a little closer to the centre of the bucket and using my fingers (usually just the index finger or the whole hand) to pitch the notes as well as moving the stick.
So, while I still need to work on the bass playing technique and possibly experiment with the instrument design to help secure the stick a little more (and thereby the intonation of the pitches/notes I play!) it is quite a simple thing to make and it makes a great bass sound!
Final say on the wash tub bass at MusiCamp? It’s definitely going to happen. I.e., if campers want to make one, it is very possible!
