The membrane is made up of irregular dense connective tissue, which is divided into two layers called the fibrous layer and the cambium layer. The cambium layer contains the progenitor cells that develop into osteoblast. The osteoblast are key in increasing the width or length of a bone.

When notes sounded together tend to be grating or unpleasant, the resulting sound is called harmony timbre x dissonance consonance 3. A group of notes played in succession with a perceivable shape x is called a melody produces harmony produces consonance produces dissonance 4.
The frequency range of sound (or, more accurately, of human hearing) is usually given as 0 Hz to 20 kHz, but our ears dont fuse very low frequency oscillations (0 Hz to 20 Hz, called the infrasonic range) into a pitch. Low frequencies just sound like beats. sine wave is a good example of a repeating pattern of amplitudes, and in some ways it is the simplest. Thats why sine waves are sometimes referred to as simple harmonic motions. Lets arbitrarily fix an amplitude scale to be from â1 to 1, so the sine wave goes from 0 to 1 to 0 to â1 to 0.
