I felt that the movies didn't really have a clear cut version of the melodies, and I really wanted to listen to that davy jone's heart melody clearly so I made two versions myself. The first is created with an organ sound, and version 2, which I prefer since it's even clearer on the melody, an anime sparkle synth thing that I created by combining a music box with another 2 synths.

I changed notes in the melody here and there to what I prefer/what my ear wants it to be like.
