巴洛克初期的奏鳴曲可由單一樂章或是多樂章而組成,當時的樂章尚未有固定的排列順序及形式,奏鳴曲的樂章可自由的跟舞曲混合。17世紀中開始,奏鳴曲可供不同場合使用之需而分為「教會奏鳴曲」(sonata da chiesa)以及「室內奏鳴曲」(sonata da camera)。「教會奏鳴曲」的風格較嚴謹,大多是由注重對位法的樂章而組成;「室內奏鳴曲」則在前奏曲後接上舞曲,風格和曲式都自由許多。從這個時候開始,「教會奏鳴曲」在樂章的排列順序上漸漸有了規範----四個樂章,各樂章的速度為慢─快─慢─快。到了科萊里(Arcangelo Corelli 1653-1713)時期,他數量豐富的小提琴奏鳴曲作品更是奠定了「教會奏鳴曲」的排列順序。「室內奏鳴曲」雖然還是沒有固定的樂章數目及順序,但是也開始沿用轉換樂章時變換速度這個規則。[2]
