It also produces a more sustained and articulate sound than other traditional materials. The Nature of Sound: Riven knows that, "Tone" can be a very subjective topic of conversation in the calling world. They also understand different tonalities will match different calling styles. In their minds, there is a common understanding of the elements that make up a pleasing tone such as volume, frequency response, overtones, definition of notes and sustain.
