Are 'Qui' mentioned, both important depending on what type of music you're making.
Personally, i'm not much of a singer, so I tend to give or at least Try to give - my melodies some sort of... 'twist' in the melody.
And as Kel mentioned "There is an old expression, that nobody whistles a lyric as they walk down the street."
I think lyrics speak more to the person, it becomes something more of a personal thing.
Let's say.. Me, as a depressed guy, I easily get drawn into the more 'morbid' & 'depressed' parts in the lyrics out there.
Because I have sort of been in the same situation as expressed in the 'lyrics' and therefore I can relate too it.
This is something Melody can't do.
However, something that Melody can do and sometimes is extra strong at... Is the fact that
it speaks with just tunes and melodies.
Sometimes it awakens and releases my inner repressed thoughts and sorrow.
In which lyrics never managed to do.
That's something that just intrigues me a lot~
Gotta love music maan!
