Bagpipes are a musical instrument most people associate with Scotland, although various forms of bagpipes have been played in lots of different countries. Someone who plays bagpipes is called a piper.

Bagpipes, as the name suggests, are made from an airtight bag with several pipes attached to it. The pipes are a chanter that you use to play tunes, and one or more drones that make a continuous noise. The piper keeps the bag full of air by blowing into it, and squeezes air out of it with their arm. You can't stop bagpipes from making noise while there is air in the bag.

A bassoon is a woodwind instrument. It typically plays in the lower registers, with a warm, dark sound. It is typically played as part of an orchestra or a smaller group that plays classical music.

Castanets are small percussion instruments that you hold in your hand. They are shaped like a pair of cockle shells, with a slightly hollowed out center. You hold them in your hand and close them quickly to make a sharp clacking noise. Castanets are usually played in pairs, one in each hand.

A chorus, also called a choir, is a group of people singing together.

A conductor is someone who directs an orchestra or other group of musicians or singers by gestures, usually by waving their hands in a special way, or waving a small stick called a baton.
