For me the most difficult thing is that I am learning melodies on guitar from some songs whose melodies were not meant to be played on guitar. Ever. They were intended mostly for keyboards or melodic percussion.
It may not be the most popular but there is a place for it. I think about the kind of music I love acoustic melodic and I guess it kind of took a bit of courage on my part to think I could be one of those songwriters.
I was looking for something a lot heavier yet melodic at the same time. Something different from heavy metal a different attitude.
