The Scoppiatori Exploder/ Burster revisited.

As I've mentioned before my building these machines is in part a practical investigation to discover how they might have sounded and played in a modern context. I've decided my build of the the Scoppiatori Exploder/ Burster is wrong. 

 

 

 

 

 

 

 

 

 

I started from the premise that it was similar to the standard intonarumori  with a drum and string but stood on its end. But I don't think there is any reason for this. I now think it is a mechanical drum probably based on designs by Leonardo da Vinci which Russolo would have been aware. Page 984r Codex Atlanticus. Which is held in the Biblioteca Ambrosiana in MIlan.

I also don't like the sounds the machine makes. I feel they don't compliment or are that different from my other three intonarumoris. It is also far too complicated a design.

Here's the machine about to be dismantled, showing the glockenspiel, 'sonic hamster wheel' and other mechanism.  

I'll  be looking to reuse some of these mechanisms or even make them into stand alone machines. 

I'm going to raise the drum and create a platform for my motor driven beaters to hit the drum. Using speed controllers this will allow for different rhythms to be set.

I've inserted a board at an angle to re-direct the sound to the horn opening. I saw this on the machines designed by Luciano Chessa at the Wigmore hall concert.  I will be keeping the levers to tighten the tone on the drum using either the design from Russolo's musikinstrument patent or a string as in the Ronzatori. The other levers can lower objects on to the drum to either 'dance' or to be hit by the motor beaters. Which will hopefully create the sounds Russolo describes in his book, The Art of Noises, '....like the bursting of objects that break and shatter' or 'make a noise similar to that of  a gasoline engine..' But I will see how my practical experimentation will go.
