[edit on Wikidata] Sounding or urethral sounding is the medical use of probes called sounds to increase the inner diameter of the urethra and to locate obstructions in it. Sounds are also used to stretch the urethra in order to receive genital piercing. Urethral sounding and urethral play are also used to refer to this practice in a sexual context. Urethral play can involve the introduction of either soft or rigid items into the meatus of the penis (as well as farther in).
The flute is the smallest and highest pitched beginning band instrument. It is a member of the woodwind family even though it is made of metal and doesnât use a reed to create the sound. In order to produce a tone on the flute, the player blows across the tone hole of the mouthpiece, allowing the air to split at the far edge of the hole. That creates a whistle sound.
