Johann Sebastian Bach - Violin Sonata No. 2 in A major, BWV 1015

Johann Sebastian Bach's Violin Sonata in A major, BWV 1015, is a part of a collection of six sonatas for violin and harpsichord, known as the "Six Sonatas for Violin and Obbligato Harpsichord," or the "Six Sonatas, BWV 1014–1019." Here are some interesting facts about this particular sonata:

1. Composition Date: Bach likely composed these sonatas during his time in Cöthen, between 1717 and 1723. They are considered among the masterpieces of chamber music from the Baroque era.

2. Unique Structure: The A major Sonata follows the traditional four-movement structure of sonatas from the Baroque period. The movements are typically marked as Adagio, Allegro, Andante un poco, and Presto.

3. Collaboration with Violinist Joseph Böhm: Some scholars believe that Bach collaborated with the renowned violinist Joseph Böhm in the creation of these sonatas. Böhm was known for his virtuosic violin playing, and the sonatas reflect a deep understanding of the instrument's capabilities.

4. Contrast of Styles: The A major Sonata, like the other sonatas in the collection, showcases Bach's ability to blend various styles. It combines elements of the sonata da chiesa (church sonata) and sonata da camera (chamber sonata), creating a rich and diverse musical experience.

5. Harpsichord as an Equal Partner: In these sonatas, Bach gives the harpsichord an equal role to the violin, departing from the usual practice of treating the keyboard instrument as an accompaniment. This reflects the evolving role of the harpsichord in chamber music during the Baroque period.

6. Expressive Depth: The A major Sonata, in particular, is known for its expressive depth, with moments of lyrical beauty and virtuosic passages that showcase the technical prowess of both the violinist and the harpsichordist.

7. Influence on Later Composers: Bach's sonatas have had a lasting influence on later composers. The unique combination of violin and harpsichord, as well as the exploration of various styles, paved the way for the development of the classical sonata in the later 18th century.

These sonatas continue to be celebrated for their musical inventiveness and the collaborative interplay between the violin and harpsichord.
