Love story is the supreme Love melody. I must have seen the movie a dozen times and "as a musician in his teens", I simply could not avoid falling for the girl who loved Bach and the Beatles... 
The tune is in E minor a particularly penetrating key when it comes to hitting the deepest corners of a man's soul.
Francis Lai is a French composers responsible for over 90 soundtracks. He significantly left a mark in his generation. Love story was such a hit that he could never reach the same high pinnacle of fame again.
The piece opens with a  brief introduction that sets the mood and background color of the tonality onto which the magnificent melody will be built.I arranged the piece starting from a piano reduction and I consider it a piece to belong up there with Romance, The godfather and Cavatina.
