The term 'English-horn kin' refers to a family of woodwind instruments, including the OBOE and oboes. The OBOE is a double-reed instrument with a conical bore, and is the most prominent member of the English-horn kin family. Oboes are typically made of wood, but can also be made of plastic or metal. They are used in orchestras, chamber music, and jazz ensembles, and have a wide range of musical applications. Oboes are also popular in folk music, and are often used in traditional Irish music.
