Musical Instruments
There are four main groups of instruments. There are many kinds of instruments in each group.
Some instruments (like guitar, violin ) use strings (弦) to make sounds. We use a bow (弓) or our fingers to play them.
Some instruments (like flute, suona ) use air from our mouths to make sounds. We blow into them and play them.
Some instruments (like horn, trumpet) use moving air and lips to make sounds. Make your lips buzz (使嗡嗡叫) to play them.
Some instruments (like drums, triangle) use sticks or hands to make sounds. Hit (敲打) them to play them.
