- [Instructor] We have learned
that there are seven names to all the notes,
ABCDEFG.
We can now add to that list of seven
all the notes with sharps and flats.
So an A,
then there could be an A sharp,
B, B sharp,
C, C sharp,
D, D sharp,
and so forth.
The same with flats.
A, A flat,
G, G flat,
F, F flat,
and so forth.
Let's go back to our piano keyboard.
From the treble clef middle C,
let's look at the octave above,
the C on the third space.
There are 12 note from the middle C
to the third space C.
These notes make up the chromatic scale.
(plays chromatic scale on piano)
Remember that between E and F
and between B and C
there isn't a black key.
Using sharps,
here are all of the names of the notes
of the chromaic scale.
C, C sharp,
D, D sharp,
E, F, F sharp,
G, G sharp,
A, A sharp, B, C.
The distance between each of these notes
is called a half step
or the interval of a semitone,
also called a minor second.
An interval is the distance between two musical pitches.
We already know one interval, an octave,
and in future lessons,
we will discuss many intervals,
but for now let's focus on the interval of a half step.
This is a fundamental building block
of all musical intervals.
A chromatic scale is made up of 12 half steps.
Now let's look a the chromatic scale
from the third space C in the treble clef
descending using flats.
C, B, B flat,
A, A flat,
G, G flat,
F, E, E flat,
D, D flat, C.
All half steps.
Towards the end of Rimsky-Korsakov's Scheherazade
in the flute part,
he writes a chromatic scale,
but he uses a combination of sharps, flats,
and naturals to make this scale,
all half steps,
a chromatic scale.
