Hey Rob, thanks for posting this.

Yeah, velocity and frequency are a tricky one to get the head around.

It also stems from the sensation of the body engaging to play higher notes louder, thus the assumption is made that the body is involved for the higher pitches themselves rather than the volume.

The Singing C Series amply demonstrates how this is an error in awareness 🙂

Cheers,
Greg.

p.s. your leadpipe is on its way!!!
