Adagio in G Minor is a beautiful piece of music. The version I always heard (and liked a lot!) was for strings and organ. I remember listening to it on repeat back in college. There is some confusion on who actually composed this piece. It is attributed to the 18th-century composer, Tomaso Albinoni but some think that the musicologist, Remo Giazotto actually composed it.
This arrangement comes from my second volume of easy arrangements. I just arranged the opening theme and tried to keep this arrangement as easy as possible.
