Clochán an Aifir or Clochán na bhFomhórach or The Giant’s Causeway is a composition for flute, oboe, and bassoon using John O’Sullivan’s Raven Temperament version 2. The score can be found here. The piece is very lightly based on the legend of The Giant’s Causeway which you can read about on wikipedia. The scale exclusively used is called Charhargan, Iranian or Double Harmonic. C Db E F G Ab B – the tuning is not 12 equal though and needs to be taken into account when analyzing the work.
