reniWhistle

The idea for this part came to my mind couple of years ago when I wanted to create somekind of a musical instrument dedicated for FFF-machines.

This whistle was one outcome and it applies 45-deg rule to recorder instrument's windway, window and labium structures. Due to the space saving design, there could be two similar structures in a beck. Also the 45-deg design creates labium much sharper than horizontal or vertical orientation in case of FFF-technology.

Thanks to the design, the whistle creates quite loud and bright high frequency tone with very little blowing (the Hz-scale is not studied). The lower tone can be created when you put your finger on the the bottom hole of the whistle. Opening and closing the hole rapidly during blowing, you can create small bird like chirping.
