What is another word for concertina?
Pronunciation: [kɒnsətˈiːnə] (IPA) 
The word "concertina" refers to a musical instrument that produces sounds through the movement of its bellows. Some synonyms for the term "concertina" include accordion, squeezebox, button box, and harmonium. All of these instruments use a bellows to produce sound, but they differ in terms of size, shape, and the number of reeds they have. The accordion is larger than a concertina and often has piano keys, while the squeezebox is typically smaller with a more limited range of notes. The button box is typically played with buttons rather than keys, and the harmonium produces its sounds through a reed organ mechanism.
