The Nashville Numbering System is used by professional and
knowledgeable amateur musicians all over the world, especially in
recording studios where it saves lots of time and trouble. It was
invented a few decades ago by the Jordanaires to make their studio
time easier and reduce studio time and therefore, cost.
It's really quite simple. It is based on the positions of the
notes of musical scales. For example, the scale of C is:
C D E F G A B C
Here is that scale with the position numbers of the notes:
1 2 3 4 5 6 7 C D E F G A B
We can leave the last note ("C") off because it is simply the
first note repeated and is already numbered '1.' Using these numbers,
if you knew the chords to a song in the Key of C, you can easily
change them to the numbers: The Chord of C would be 1, D would be 2,
E would be 3, etc. G7 can be written 57 with the numbers. Fm would
be 4m. Bb7 would be 7b7, and so on.
What is the advantage to doing this? Well, suppose you know
the numbers as they apply to all 12 keys in music. If you sing a
song in the Key of C, and a friend comes along who sings that song
in the Key of E - you don't have to even think about what the
chords are, because you are thinking of them as numbers. Since you
know what chords those numbers equate to in both of those keys, you
automatically know all of the chords instantly. If you don't know
the numbers, you have to go through this kind of thought process:
Well, if I'm playing the chord of C in the Key of C, then I have to play the Chord of E in the Key of E.
Now here is a change to the chord of F in "C" - let's see, that would be... er, um... A in the Key of E.
And when the chord changes to Am in the Key of C, well... hmmm... C#m in "E"?? And so on.
Here is a table listing the scales in the most often used keys
for guitar:
KEY 1 2 3 4 5 6 7 C C D E F G A B D D E F# G A B C# Eb Eb F G Ab Bb C Db E E F# G# A B C# D# F F G A Bb C D E G G A B C D E F# A A B C# D E F# G# Bb Bb C D Eb F G A B B C# D# E F# G# A#
Let's look at an actual example. Here is a song most people
are familiar with - "Blue Eyes Crying In the Rain," recorded by
Willie Nelson. It is in 4/4 time, and I will place chords for the
first beat of each measure. Here it is with letter names for the
Key of C:
| C |
| In the twilight glow I see her, |
| G7 | C |
| Blue eyes crying in the | rain |
| C |
| When we kissed goodbye and parted, |
| G7 | C | |
| I | knew we'd never meet a | gain |
| F |
| Love is like a dying ember, |
| C | G7 |
| only memories re | main |
| C |
| Through the ages I'll remember, |
| G7 | C |
| blue eyes crying in the | rain. |
Here is the same thing with numbers:
| 1 | 1 | 1 | 1 |
| In the | twilight glow I | see her, |
| 57 | 57 | 1 | 1 |
| Blue eyes | crying in the | rain |
| 1 | 1 | 1 | 1 |
| When we | kissed goodbye and | parted, |
| 57 | 57 | 1 | 1 | |
| I | knew we'd | never meet a | gain |
| 4 | 4 | 4 | 4 |
| Love is | like a dying | ember, |
| 1 | 1 | 57 | 57 |
| only | memories re | main |
| 1 | 1 | 1 | 1 |
| Through the | ages I'll re | member, |
| 57 | 57 | 1 | 1 |
| blue eyes | crying in the | rain. |
Now, since each measure of the song is indicated with a chord
in these examples, we can also show the chord progression
separately from the lyrics by showing each measure like this:
1 1 1 1 57 57 1 1 1 1 1 1 57 57 1 1 4 4 4 4 1 1 57 57 1 1 1 1 57 57 1 1
Some songs have chord changes within a measure. These are
shown by placing parentheses around the measure, like this:
1 (1 17) 4 4
Play just a little every day - you will have the numbers memorized in no
time, probably within a month. And I mean for every key you play in!
You will never be sorry you did. If you play in a band, or jam with a
group, try to get the other members to start using the numbers too, and
communicate with numbers instead of letters. Then you can tell each
other chord changes with the same numbers IN ANY KEY!
