Cloud Cello

So, you take an unsuspecting cello, remove all the strings except one and place it in a stand. Instead of a conventional bow, use something with a bit more texture and bite – in this case, a ball of coarse garden string sounded best. Stringing a standard bow with garden twine doesn’t work, you’d need an impossible 10-metre bow to play a smooth note (I know it’s impossible because I tried to make one!).

After many experiments and cups of coffee, a retractable dog lead, an elaborate pulley system and a classic vintage fishing reel came to the rescue. This system can hold long lengths of string under tension and be drawn evenly over the cello string to produce a usable tone.

Next step is to rig up some suitable mics. A contact mic near the bridge gave good body, and a large diaphragm condenser near the string picked up the ‘grist’. Then using a capo for accurate tuning, thousands of passes were recorded to get enough samples for 5 x round robins per note plus conventionally bowed accents and col legno notes for extra flavour.

The final step is to form the Clouds by pushing each note 100% wet through a bespoke swirly setting on my Strymon Big Sky reverb pedal, and then do the same thing all over again with a different setting for 200% wetness.
