The viola sonata is a
sonata for
viola, sometimes with other instruments, usually
piano. The earliest viola sonatas are difficult to date
for a number of reasons:
- in the Baroque era, there were many works written for the viola da gamba, including sonatas (the most famous being Johann Sebastian Bach's three, now most often played on the cello)
- in the
Classical era and early
Romantic, there were few works written with viola
specifically in mind as solo instrument; it was more
typical to publish a work or set, like
Georges Onslow's opus 16 cello sonatas, or Johannes
Brahms's opus 120 clarinet sonatas in the
late 19th century, that specified the viola as an
alternate.
- The Brahms may be the first repertory sonatas for the instrument, alternates with an independent life and a performance history.
