I was going onto adding 7ths but this might be a good time to talk
a little more about Intervals first.
Simply put, intervals are the distances between pitches.
That's the different sounds you hear from starting at C and going up
the diatonic and chromatic scale.
Lets look at the pitches found in the C scale.
We start with ...C D E F G A B C - simple enough.
But there are
more than this.
We also have C# D# F# G# A#
now there are flats but C# is also Db
D# is also Eb
F# is also Gb
G# is also Ab
A# is also Bb
So added up.. C C# D D# E F F# G G# A A# B C
Between each of the notes or pitch sounds, there is a space and that
space is called an INTERVAL. If you picked up your guitar, and if you
had an electronic tuner clipped to your Head stock, if you hit a C note
on the 2nd string 1st fret, then proceeded one fret at a time up the neck,
you would be playing each of the pitch/notes. Each fret
would be a half step in distance. These steps have names along with
roman numerals.
The following will show them.
1st fret 2nd string tuned to standard, or the B string.
C to C is called a Unison (perfect)
C to C# minor 2nd or.. ii
C to D MAJOR 2nd II
C to D# minor 3rd iii
C to E MAJOR 3rd III
C to F PERFECT 4th IV
C to F# Diminished 5th v
C to G PERFECT 5th V
C to G# minor 6th vi
C to A MAJOR 6th VI
C to A# minor 7th vii
C to B MAJOR 7th VII
C to C OCTAVE
The last C should not be confused with the first one as it has moved
up the scale and is now an octave above the first C.
on a staff it would appear thus;
