Hedwig's Theme is a leitmotif composed for the Harry Potter film series by John Williams. It is one of the most recognizable musical themes of the Harry Potter film series. The theme is quite memorable, with its bright and enchanting melody.
The basic notes of the theme are F, G, A-flat, B-flat, and C. This is the most common version of the melody, but other arrangements include additional notes or alternate melodies.
The main melody begins with a three note phrase in F. This is then repeated twice with a slight flourish between the repetitions. The second phrase begins in B-flat and moves through A-flat and G. Again, this phrase is repeated twice with a flourish. These two phrases form the backbone of the entire theme.
The last phrase is more playful and melodic. It moves from C to A-flat and back down to F, before finishing with a gentle flourish.
The theme as a whole is light and uplifting, with a lot of joy and wonder. This is what makes it so memorable, and why it has become such an iconic symbol of the Harry Potter series.
