Highly regarded as soloists as well as chamber musicians, Frank Peter Zimmermann and Martin Helmchen are also known for an unostentatious and selfless musicianship which never obscures the music they are performing. When they started their collaboration in 2018, it was with the aim of playing and recording Beethoven's 12 violin sonatas. A series of recitals at prestigious venues and festivals was followed by the first recording sessions, which took place in September 2019, with results that can be heard on this disc. Towards the end of the 18th century, the violin sonata had become one of the most important forms of chamber music in Viennese Classicism. Admittedly, Haydn did not make a single contribution to the genre, but Mozart composed no less than 36 violin sonatas, including the early childhood pieces. Beethoven's first pieces for violin and piano were also early, but by the time he composed his first three sonatas he was well on his way to maturity. In formal terms the Opus 12 sonatas are perhaps rooted in Mozartian ground, but they go far beyond that role model with their numerous moments of melodic and harmonic surprise. Published in 1798, the three sonatas quickly became very popular. Composed only a couple of years later, the A minor sonata, Op. 23, was of a more melancholic and uneasy character and never reached the same popularity as the Op. 12 set – or the sonata that followed: the famous 'Spring' Sonata included on the next instalment of this 3-disc series.
