Which parts lose you? I'd like to know so I can improve upon them in the future.
I didn't have any theme in mind as a reference for the second melody, but it uses a variation of a really common rhythm (two dotted quarter notes followed by a quarter note, commonly called a "pop clave" or "half clave")...I used that rhythm a lot in the accompaniment sections, but that's one of the rare places where it's explicitly in a melody. (One of the most obvious songs that uses that rhythm, and the one I use as an example, is "Wait for It" from Hamilton.)
the melody i'm talking about is the melody in your Options track. The pop clave is there, but so many submissions have used it already (including mine) that i don't really notice it anymore.
but it's really just the melody there that's ringing a bell. (this section, transposed to a minor, if it makes sense: a g f e d e, f e, d e e f e f g a) i've been listening to a lot of legend of zelda music lately so maybe there's something similar in there and my brain is grabbing onto it. :shrug:
well, i'll let you know if i identify it, and i'll try and get back to you later about the harmonies.
