There’s some debate as to when Bach wrote his A minor Violin Concerto [BWV 1041] – was it earlier in Köthen (1717-23) or later in Leipzig (1729-30)? The work is clearly based on the concertos of Vivaldi but, being a northerner, Bach adds a whole new layer of musical complexity to the Italian’s simple but effective structure. You can, for example, get a visual notion of this increased knottiness happening at the top, architectural, level from this ground-plan of Bach’s first movement…

Unlike Bach, Handel espoused the Corelli multi-movement model of the concerto, writing his twelve Op. 6 Concerti Grossi as a tribute to the Italian composer’s Op. 6 (which – if you remember – also consisted of twelve concertante works for strings and continuo). The Handel, while (as ever) not quite as challenging as the Bach, still has its moments…

The concerto grosso eventually, with a bit(?) of tweaking, transformed itself into the sinfonia concertante (aka the double or triple concerto). But, in the 20th century, there was a revival of interest in the old form. The Swiss/American composer, Ernest Bloch, wrote two such works, the first for strings with obbligato piano and this, the second, for concertante strings and solo string quartet.
