"Black Forest's" timbre is a bit unusual for Siladia's works. It doesn't chirr as much as usually his works do. Or maybe if we imagine that the chirring was slowed down for two times, or for five times, or maybe even ten!.. then we realize that it might still be present in the tone, But it transformed to some interfering f sound waves... Response and control are more than fine, as they usually are at this craftsman's works.
