This is a single song
"Hedwig's Theme" is the character-specific theme (leitmotif) composed for orchestra by John Williams for the Warner Brothers film, Harry Potter and the Sorcerer's Stone, and is interpolated throughout the rest of the Harry Potter film series. While the original orchestration contains no piano, this piano solo arrangement (for 2 hands) composed and performed by Jarrod Radnich captures the magical and at times sprightly aura within the film while at the same time conveying the awesome power that resonates throughout the full orchestral score.
