Intervals Lesson by flyinglibra51

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;
