In music there is an infinity of undecidables
More evidence of how artwork changes the sound of CDs comes from this new release on the Spanish Enchiriadis label. Músicas Viajeras is a journey through the music of Christians, Sephardic and Muslim Spain performed by chamber choir Musica Ficta and early music ensemble Ensemble Fontegara with sonic enhancement from Juan Lucas' cover photography. Those who doubt that graphics can influence sound or that frequencies we can't hear alter those we can hear should reflect on Gödel's theorem. This states, when expressed in layman's language, that in any consistent axiomatic system there are undecidable propositions; moreover not only are there undecidables, but there is an infinity of undecidables. Which means music exists only in constant flow and flux.
