## Understanding Intervals And Accidentals

An interval is the distance from one note to another note either above or below the original note.

Now, the two most basic and most important intervals to know about are a half step and a whole step.

Half Step

A half step is the distance from one note to the very next note either directly above or below the original pitch.

Now, if I was to for instance start on the note B and go up one half step I would end up on the note C. The very next note above the note B is C.

Likewise, if I was to start on the note C and go down one half step I would end up on the note B. The very next note below the note C is B.

Let’s try it again this time starting on the note E.

Starting on E and going up one half step would take you to the note F. The very next note directly above the note E is F.

And just like earlier if our original note was F and we went down one half step we would end up on the note E. The next note directly below the note F is E.

This is very important to remember. B and C, and E and F, are the only two sets of natural notes which are separated by half steps. All other natural notes are separated by whole steps.

Now that we know what a half step is a whole step will be much easier to understand.

Whole Step

A whole step is the distance of two consecutive half steps.

Let’s start on the note A. If we go up one half step from the note A it will take us to this black key.

Now, we know that a
