The hypothalamus (from Greek á½ÏÏ, under and Î¸Î¬Î»Î±Î¼Î¿Ï, thalamus) is a portion of the brain that contains a number of small nuclei with a variety of functions. One of the most important functions of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland (hypophysis).
Instrument Families in Music The instrument families are made up of four main families: woodwinds, brass, strings, and percussion. The pictures below include some of the instruments in each musical family. The instruments have an audio file to listen to the instrument sound. Scroll down the page to see all of the instruments. Woodwind Family - Woodwind instruments produce a sound by blowing into a mouthpiece. Some woodwind instruments use a reed to make the sounds play.

How Brass Instruments Work. Brass instruments are any tube that can be played with the lips. They're not always brass, as instruments like the Aborigine digeridoo, and the conch shell, are made of wood, and shell, respectively. However, most modern brass instruments have a long, cone-shaped tube and flaring bell. Usually the tube is coiled in order to make it easier to hold. Often they have valves or other mechanisms to extend the range of notes that can be played with the instrument. Making Sound . Modern brass instruments produce sound through a metal mouthpiece. The mouthpiece is similar on most brass instruments, usually varying only in size. Sound is produced by placing the lips on the mouthpiece and blowing while vibrating the lips. The larger the mouthpiece, the lower the sound of the instrument. Playing Different Notes
