Sounds of Silence

A European Harmonising Project

"We know what we are, but know not what we may be." - William Shakespeare

What can silence tell us about ourselves? Has the sound frequency of music anything to do with the reality we face? What does it take to become fully harmonized with the citizens of our continents? The new harmonic pianotuning presented by Sounds of Silence, is based on the recently created 12-based 'Krystal' tuning. Experience the amazing sounds brought to you by professional musicians deliberately using two classic Erard grand pianos from around 1870.
