Just write

I was chatting with a composer friend of mine the other day and we both are writing pieces with a similar approach right now.

We’re just writing.

Not much planning other than some mental things.

Thinking of a few ideas ahead of time, but that’s the extent of the planning.

And so far for me it’s going great. I started writing a string orchestra piece and writing it this way is perfect right now.

I think it’s important to experiment with different writing styles and see which ones work best for you. And maybe those will change. But experiment with different ways of writing. Write the melody first. For something else start with the chords or the harmony. Another piece might start with the texture.

Some you may plan in a lot of detail. Planning out every single section and how they’re related.

Other pieces you may not plan out at all.

That’s what I’m doing.

Give it a shot. Maybe you’ll find that you like composing in some ways that you hadn’t expected to enjoy. Or you might find, as I have, that some types of pieces and some styles work better for certain styles of writing. While other styles or conceptual ideas don’t work as well with some styles of writing.
