Bassoons are usually made from maple wood. Like the oboe the bassoon is played with a double reed. To make a sound the player blows through the double reed which is attached to a crook leading into the main body of the instrument. Bassoon players change the pitch of the notes by pressing different combinations of keys.
The bodies of the string instruments, which are hollow inside to allow sound to vibrate within them, are made of different kinds of wood, but the part of the instrument that makes the sound is the strings, which are made of nylon, steel or sometimes gut. The strings are played most often by drawing a bow across them.
