There are many different kinds of musical instruments. They are divided into three main classes
according to the way they are played. For example, some instruments are played by blowing air into
them. These are called wind instruments. In some of these the air is made to vibrate inside a wooden
tube and these are said to be of the woodwind family. The examples of this family are the flute, the
clarinet and the bassoon. Other
instruments are made of brass: the trumpet and the horn are the
examples. There are also various other wind instruments such as the mouth organ and the bagpipes.
Some instruments are played by banging or striking them. One obvious example is the drum, of which
there are various kinds. Instruments like this are called percussion instruments.
The last big group of instruments are the ones which have strings. There are two main kinds of stringed
instruments those in which the music is made by plucking the strings and those where the player draws
a bow across the strings. Examples of the former are the harp and the guitar and that of the latter are
the violin and the cello.​
