Traditional / experimental practice

The Architecture of Echo · The Underground Cave

The same phrase in a large cave: the first reflection arrives late (120 ms), the tail lasts six seconds and is dark; the reverberation sounds stronger than the bells themselves. The space is a representation: the reverberation is generated in code, not measured in a real building. A listening practice with no claim of any effect.
