What is composition and orchestration, and what is notation software?

Simply put, "composing" means "making" music that produces "relatively new" music.

In general, orchestration is a link in composition, a kind of musical technical thinking.

For example: the melody, harmony, etc. that have been determined, what instrument to use to play it;

Or conversely, design a suitable melody for the instrument; harmony; sound shape; playing method, etc. , this falls into the category of orchestration thinking.

This is of course for traditional music. Just like a traditional painter, he sketches first and then colors. Most traditional composers also work on the piano first, and then process it into a band score with rich timbre. Of course, in modern times, it is possible to just play with colors regardless of sketching.

Notation software is an alternative tool to the traditional composer pen and music paper. While it is more efficient, it also has the disadvantage of disconnecting vision and hearing. For example, sibeiliu s is a popular professional notation software now.
