A reed pipe comprises a metal tongue (the reed) which rests against a shallot, in which is carved a tunnel. The reed and shallot are held in place by a wooden wedge. This assembly protrudes from the underside of the block and hangs down into the boot. A tuning wire is inserted through the boot and is bent to hold the reed against the shallot.
A hand-pumped Indian harmonium, of the type used in South Asia, here used at a European jazz festival.. The pump organ or reed organ is a type of organ using free-reeds that generates sound as air flows past the free-reeds, the vibrating pieces of thin metal in a frame.
A flask containing human cerebral organoids. A neural, or brain organoid, describes an artificially grown, in vitro, tissue resembling parts of the human brain.Neural organoids are created by culturing pluripotent stem cells into a three-dimensional culture that can be maintained for years.
Vox humana pipes. The vox humana (Latin for "human voice"; also "voz humana" in Spanish and Portuguese, "voix humaine" in French and "voce umana" in Italian, although "voce umana" is also a term for a celeste stop, q.v.) is a short-resonator reed stop on the pipe organ, so named because of its supposed resemblance to the human voice.

The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It consists of nervous tissue and is typically located in the head ( cephalization ), usually near organs for special senses such as vision , hearing and olfaction .
The Indian harmonium, hand harmonium, samvadini, peti ("box"), or vaja, often just called a harmonium, is a small and portable hand-pumped reed organ which is very popular in the Indian subcontinent. [1] The sound resembles an accordion or other bellows driven free-reed aerophones. [1]
A reed is fixed by one end in a close-fitting frame. The loose end has a slight rising bend. Air depression is applied under the reed; the reed prevents air flow, except for a small, high-velocity flow at the tip. The reed is sucked through the opening, allowing the air to pass. The elasticity of the reed forces it back through the frame.
Although these organ reeds were originally designed and manufactured for American style suction organs they became the favored reeds for their tone quality and tuning stability in Indian hand pumped harmoniums which work on an air pressure system. In order for them to be attached to the Indian harmonium reed board (as opposed to sliding into ...
