So in order to be able to compose orchestral music, we have to understand how the orchestra works,
what are the typical sections, what instruments are in this section?
How did those instruments work?
Certain instruments will have a particular range that they can play.
So, for example, if you want to create a high melody using a tuba, it's not going to work because
the tubas range is in the bass frequencies.
When we talk about notes, we named the note and the octave number where that note is located.
So, for example, CIFOR is widely considered to be middle C or the C in the middle of the piano.
It is the C present in the fourth octave and therefore we call it C for.
The higher the number, the higher the pitch and the lower the number, the lower the pitch.
So C three would be lower than C four, it would be an octave lower, in fact, and C five would be
an octave higher than C four.
Now, this isn't that important for us because we're actually going to be using virtual instruments
and a computer.
So you can probably ignore the ranges when you're working within your virtual orchestra.
But if you ever plan to write for a real orchestra or maybe your score is being adapted for a real orchestra,
you will need to be aware of the different instrument ranges.
So let's move on now and we'll take a look at different types of orchestras, what sections they have
and how they sound.
