Q: And how does the harmony work? (i realize this is 3 questions, but it's really just 1, still i apologize)
A: the melody is C#, B, A, G# (G), G#. and each note is harmonized the same exact way. the first cluster is A, C# and D. the second cluster is G B and C. and so on. all the same shape, following the melody. ignoring the key, for that moment
