In the late 1750s to early 1760s, a period when Emanuel Bach was entering his forties, this phase of his musical life undoubtedly played a significant role. Particularly notable is the Sonatina in B-flat Major, a piece that represents a rare genre not commonly seen in his previous series. The composer did not recognize these "Sonatinas" as "concertos." Although they are structured for a solo keyboard instrument and a standard string quartet ensemble, they differ from what he understood by the term "concerto." All the Sonatinas include wind instrument parts and adopt a style that is clearly lighter and more playful than that of concertos. Composed in just three years from 1762 to 1764, these pieces were likely intended for public performances in spaces considerably larger than the private rooms Bach used before the war.
In this piece, as with many Sonatinas, the string parts are complemented by two flutes and two horns, increasing the ensembleʼs volume. However, this piece is unique in that it employs two solo keyboard instruments, making it a rare example among Bachʼs Sonatinas. It is the second work Bach composed for two keyboard instruments (the first being a concerto written over 20 years earlier) and represents his first attempt to combine the timbres of the harpsichord and piano. This piece is particularly distinguished from a concerto in its movement structure. Following the typical Sonatina pattern, it begins with a relatively slow, dance-like movement, followed by a fast movement, and concludes with a somewhat slower movement. Overall, it is a light and charming work, well-suited for the public.
In the solo parts of the Sonatina in B-flat Major Wq 110 (H459), only the terms "Cembalo Primo" and "Cembalo Secondo" are indicated. In Bachʼs time, the word "Cembalo" was a general term referring to keyboard instruments, leaving us with the option to record this work using two different instruments.
