Details: While there is no doubt today that this music originates from Bach, due to numerous deviations from the usual viola da gamba music of his time, it is considered likely that he originally had a different ensemble in mind, or that these works existed in other instrumentation before he adapted them for the viola da gamba. This was a common practice then, just as it makes sense today to arrange "classics" for all kinds of other instruments, preserving their original character while simultaneously creating possibilities for new tonal aspects. It was in precisely this spirit that Kurt Gold and Reinhard Latzko arranged Bach's sonatas for their instruments. In Astor Piazzolla, we encounter one of Argentina's most prominent and innovative musicians, who stands out as a bandoneon player, composer and founder of the "Tango Nuevo". This category includes "Le Grand Tango", which was commissioned in 1982 by the Russian cello virtuoso Mstislav Rostropovich.
