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. Content on this page requires a newer version of Adobe Flash Player. Brass Family - Brass instruments are played by 'buzzing' the lips into the mouthpiece.
The main difference between brass instruments and other instruments is how the vibration to create the sound and notes is made. With a brass instrument the vibration is created by the lips of the musician. By pressing the lips up against the mouthpiece and blowing, a vibration is created. The rest of the horn helps to amplify the noise and create different notes.
