Intervals, the Fretboard and the Strings


You should know how intervals relate to the fretboard. Why? Because knowing how intervals relate to the fretboard is the secret to guitar mastery. And knowing intervals leads to music mastery.

Intervals


Going from one tone to the next is called an interval. An interval expresses a relationship between successive tones.

Interval Names

There are only a few kinds of intervals: perfect, major, minor, augmented or diminshed. 

Each interval gets a name: 


minor 2nd = flatted 2nd = ♭2 = half 2
Major 2nd = 2nd
minor 3rd = flatted 3rd = ♭3 = half 3
Major 3rd = 3rd
Perfect 4th = 4th
Tritone = flatted fifth = ♭5 = augmented fourth = ♯4 = half 5
Perfect 5th = 5th
minor 6th = flatted 6th = ♭6 = half 6
Major 6th = 6th
minor 7th = flatted 7th = ♭7 = half 7
Major 7th = 7th
Perfect 8th = 8th

Interval names get abbreviated: 



  • m for minor, M for Major, P for Perfect, TT for Tritone
  • P1 means the zero interval, also said as Perfect 1 or most often as Unison.


The Tritone, Augmented and Diminished


Some call the Tritone an Augmented 4th. Some call the Tritone a Diminished 5th.

  • Augmented gets abbreviated as A. 
  • Diminished gets abbreviated as D.

Intervals and the Guitar

Playing from one fret to the next,  whether on the same string or on another string is how you play any interval.



Intervals and Frets


The intervals between the open string tones and the frets are fixed. So, for example, a F on D will be a m3 from D, always. As well, a B♭ on G will be a m3 from G, always.

open string = P1 = unison
1st fret = m2 = ♭2 = half 2
2nd fret = M2 = 2
3rd fret = m3 = ♭3 = half 3
4th fret = M3 = 3
5th fret = P4 = 4
6th fret = TT = ♭5 = half 5
7th fret = P5 = 5
8th fret = m6 = ♭6 = half 6
9th fret = M6 = 6
10th fret = m7 = ♭7 = half 7
11th fret = M7 = 7
12th fret = P8 = 8 = octave


Intervals and Chromatic Scales


If you know your chromatic scales, you can find tones on the fret board with ease.

For example: C is a m6 on E  because E chromatic scale: 
E F G♭ G A♭ A B♭ B C D♭ D E♭ E
and the intervals of every chromatic scale as a diatonic scale:
P1 m2 2 m3 3 4 TT 5 m6 6 m7 7 8

And so all of these are true:

C is a m3 on A
C is a m7 on D
C is a P4 on G
C is a m2 on B

In this picture, the minor tones have a bar above the number. The major tones are without a bar and the perfect tones have been circled.



If you know that C is a m3 on A, then you know you can find C on the 3rd fret on the A string. See?

Intervals and Inversion


On the fret board, the same count of frets, also known as distance, gets a different interval name depending on going up or going down.
m2 ↔ M7
M2 ↔ m7
m3 ↔ M6
M3 ↔ m6
P5 ↔ P4
TT ↔ TT 
P4 ↔ P5
m6 ↔ M3
M6 ↔ m3
m7 ↔  M2
M7 ↔ m2
Keep these pairs in mind: 2 & 7, 3 & 6, 4 & 5 and then swap the minor for major.

Intervals Between the Strings

Low pitch E (the E under your chin) to A = P4
A to D = P4
D to G = P4
G to B = M3.
B to high pitch E  (The E closest to the floor) = P4. 
Remember, intervals have inverse relationships. So playing the open strings from high pitch E (the E closed to the floor) to low E:
E to B = P5
B to G = m6
G to D = P5
D to A = P5
A to E = P5
In the Riptide Guitar method, we call the E, A, D, G strings the P4 strings. We call the B string the M3 string.

Traveling on the Fret Board and Strings


Going up the neck (→) is the same as going toward the bridge. The pitch gets higher going up.

Going down the neck (←) is the same as going toward the headstock. The pitch gets lower going down.

Going down a string (↓) is the same as going toward the floor. The pitch gets higher.

Going down a string (↓) is the same as going toward the floor. The pitch gets higher.

Intervals on the Same String



These are the interval relationships from one fret to another on the same string within the practical limit of the stretch of your hand.

up 1 fret → m2 (e.g., A → A♯)
up 2 frets → M2 (e.g., A → B)
up 3 frets → m3 (e.g., A → C)
up 4 frets → M3 (e.g., A → D♯)
down 1 fret ← M7 (e.g., A♭ ← A)
down 2 frets ← m7   (e.g., G ← A)
down 3 frets ← M6   (e.g., G♭ ← A)
down 4 frets ← m6   (e.g., F ← A)

Intervals and Frets


These are the interval relationships from one fret to another on the same string within the practical limit of the stretch of your hand.



↓ 1 string, ← 1 fret = M3 = 3
↓ 1 string, ← 2 frets = m3  = half 3
↓ 1 string, ← 3 frets = M2 = 2
↓ 1 string, ← 4 frets = m2 = half 2
↓ 1 string, → 1 fret = TT = half 5
↓ 1 string, → 2 frets = P5 = 5
↓ 1 string, → 3 frets = m6 = half 6
↓ 1 string, → 4 frets = M6 = 6
