Thread: Question about composition music

Hello I'm new in this site and thankyou for who designed it
I'm playing classic guitar and I'm working to compose a piece music
but I found hard because I dont know about the basic of composition music
I have been composing my piece ,just melody tune and I want to complete with harmony
I dont know how to explain what I mean but I'll try
More clearly: if you hear the piece music - Romance for composer Anonnym - you can hear
4 strings and the melody strings is E 1st and other is like harmony or ATTENDANT sound
may be there are many mistakes in my explanation ,but my education music is very little
and thankyou for all

It's very hard to explain harmony in one post. You should Google "Music theory". It will help you alot.
