Ethnic music - Adding knowledge!

Today I was thinking about making songs for St. Patrik’s Day, to put on Audiojungle, Pond5, etc … and I realized how difficult it is to compose a song that does not have characteristics of my culture, I was not sure which instrument to use for this music, or the correct rhythm.

I’m Brazilian and I know rhythms like samba and bossa nova. And as we can exchange information here with people from all over the world, I thought about using this topic to talk about the particularities of our local music …

What it represents and add culture to each other. What do you think?
