Arioso

In classical music, arioso is a category of solo vocal piece, usually occurring in an opera or oratorio, falling somewhere between recitative and aria in style. Literally, arioso means airy. The term arose in the 16th century along with the aforementioned styles and monody. It is commonly confused with recitativo accompagnato.

Arioso is similar to recitative due to its unrestrained structure and inflexions, close to those of speech. It differs, however, in its rhythm. Arioso is similar to aria in its melodic form, both being closer to singing than recitative; however, they differ in form, arioso generally not resorting to the process of repetition.
