No offense, but one person does not get to redefine what nearly 300 years of history has etched in stone.
Call them 'Impressions', 'Pieces', 'Diversions' or whatever. But do not call them sonatas if they do not fir the form. Like I said, you might as well be writing 4/4 waltzes.
I think you might be getting Sonata and Sonata form confused. I stand by my decision to call them Sonatas but I will agree that they do not perfectly fit the traditional definition of Sonata form. I will say that they are loosely based up sonata form. Keep in mind, even some of the late sonatas by Beethoven and Scriabin began to break down the concepts behind sonata form.
Encyclopedia Britannica: Sonata
Sonata, type of musical composition, usually for a solo instrument or a small instrumental ensemble, that typically consists of two to four movements, or sections, each in a related key but with a unique musical character.
Deriving from the past participle of the Italian verb sonare, “to sound,” the term sonata originally denoted a composition played on instruments, as opposed to one that was cantata, or “sung,” by voices. Its first such use was in 1561, when it was applied to a suite of dances for lute. The term has since acquired other meanings that can easily cause confusion. It can mean a composition in two or more movements, or separate sections, played by a small group of instruments, having no more than three independent parts. Most frequently it refers to such a piece for one or two instruments, such as Beethoven’s Moonlight Sonata (1801) for piano. By extension, sonata can also refer to a composition for a larger instrumental group having more than two or three parts, such as a string quartet or an orchestra, provided that the composition is based on principles of musical form that from the mid-18th century were used in sonatas for small instrumental groups. The term has been more loosely applied to 20th-century works, whether or not they rely on 18th-century principles.
Sonata Form
Quite distinct from all of the preceding, however, is the use of the term in “sonata form.” This denotes a particular form, or method of musical organization, typically used in one or more movements of multi movement instrumental works written since the beginning of the Classical period (the period of Mozart, Haydn, and Beethoven) in the mid-18th century. Such works include sonatas, string quartets and other chamber music, and symphonies.
Sonata form, also called first-movement form or sonata-allegro form, musical structure that is most strongly associated with the first movement of various Western instrumental genres, notably, sonatas, symphonies, and string quartets. Maturing in the second half of the 18th century, it provided the instrumental vehicle for much of the most profound musical thought until about the middle of the 19th century, and it continued to figure prominently in the methods of many later composers.
Although sonata form is sometimes called first-movement form, the first movements of multi movement works are not always in sonata form, nor does the form occur only in first movements. Likewise, the variant sonata-allegro form is misleading, for it need not be in a quick tempo such as allegro.
