Muscles are the organs of motion and consist of bundles or fasciculi of parallel reddish contractile fibres. Toward the end of the muscle the fibres are so modified that they form a white cord or tendon of great density and strength. This tendon is attached to the bone so strongly that it is almost impossible to detach it. Sometimes a tendon spreads out like a flat sheet or thick membrane; it is then called fascia or aponeurosis. The fibres of a muscle have the power of contracting and relaxing under different stimuli sent to them by nerves. Muscular contractions cause them to move the bones, and consequently the limbs and body, in such direction as the brain and nerves command. Contraction is the special function of the muscles; all movements are performed by them. There are three kinds of muscle tissue: striated muscle, smooth muscle, and cardiac muscle. Most of the body' s muscle consists of striated muscle which is the skeletal muscle. It is also called voluntary muscle because it can be consciously controlled via the central nervous system.
Smooth muscle is the muscle of the internal organs and is called involuntary because it is not under voluntary control. Cardiac muscle is a special type of muscle found only in the heart. It consists of linked fibres that contract in unison producing the heartbeat.

Below the main part of the head are muscles of the neck. These muscles extend both deep and superficially from the base of the skull to the back. They work together to flex the head when nodding, take part in breathing, and act in unison with the eye muscles, causing the head to turn from side to side with the eyes.

The bagpipe is a musical wind-instrument of very great antiquity, having been used among the ancient Greeks, and being a favourite instrument over Europe generally in the 15th century. It still continues in use among the country people of Poland, Italy, the south of France, and in Scotland and Ireland. Though now often regarded as the national instrument of Scotland, especially Celtic Scotland, it is only Scottish by adoption, being introduced into that country from England. It consists of a leathern bag, which receives the air from the mouth, or from bellows; and of pipes, into which the air is pressed from the bag by the performer's elbow. In the common or Highland form one pipe (called the chanter) plays the melody; of the three others (called drones) two are in unison with the lowest A of the chanter, and the third and longest an octave lower, the sound being produced by means of reeds. The chanter has eight holes, which the performer stops and opens at pleasure, but the scale is imperfect and the tone harsh. The Highland bagpipe is a powerful instrument, and calls for great exertion of the lungs in order that the air may be supplied in sufficient quantity. There are several other species of bagpipes, as the soft and melodious Irish bagpipe, supplied with wind by a bellows, and having several keyed drones and a keyed chanter; the old English bagpipe (now no longer used); the Italian bagpipe, a very rude instrument, etc. The Irish bagpipe is, musically speaking, the most perfect of all.

In music the beat is the beating or pulsation resulting from the joint vibrations of two sounds of the same strength, and all but in unison. The term is also applied to a short shake or transient grace-note struck immediately before the note it is intended to ornament.
