Sinfoniettas are orchestral pieces that are shorter and more compact than a symphony. There are many synonyms for sinfoniettas that can be used interchangeably depending on the context. These synonyms include chamber symphonies, symphoniettas, serenades, divertimenti, and cassations. Each of these terms refers to a smaller-scale orchestral composition that typically features fewer musicians and is designed to be performed in a more intimate setting. While sinfoniettas may be less well-known than other orchestral works, they offer a delightful and accessible introduction to classical music for those who may be intimidated by the scale and complexity of a full symphony.
