In Garlic Theatre's new show, There's A Monster In My Piano, there is a toy piano. It's a wonderful little thing with a wooden body and beaters with an 'old-fashioned' plastic look. It's French made and, without knowing the make and model off hand, I'd guess it was built in the 1950s. The 'strings' are metal rods and there are no dampers.
I have been sampling the instrument, note by note, with varying attack and collecting various sounds for use as effects. Playing the piano softly is a challenge as too little force fails to throw the hammers against the rods. My favourite sound effect is created by tipping the piano backwards so the hammers fall against the rods in a random fashion.
To give a flavour of the instrument I recorded a snatch of Bach (I ran out of notes with which to play further) and a 12-Bar. Perhaps I should have picked it up off the floor first; my piano playing is generally bad but seldom this awful The battery on top of the piano in one of the pictures is AA, just to give some idea of scale.
