The Nashville Number charts are a standard way to write out chord progressions and arrangements for songs that do not require reading music.
This approach came about in the 1950s as the studio crew known as the A Team was recording around the clock in studios like the Quonset Hut and RCA Studio B with artists like Elvis, Brenda Lee, Roy Orbison, Marty Robbins, and countless other Country, Pop and Rock artists. I believe credit for this system lies with the Vocal group the Jordanaires who sang backup on most of the record dates in Nashville at that time.
Simply put, each scale tone is given an Arabic numeral. Thus, a C scale would be 1-2-3-4-5-6-7 instead of C-D-E-F-G-A-B. Each chord is assumed to be major, unlike the diatonic chord progression. My theory about this is that the lion's share of most Nashville songs were written on guitar with the "3 grips" instead of piano as the Brill Building and Tin Pan Alley writers were doing. A progression might be C-C-D7-G instead of C-C-Dm7-G7 as you would naturally play in key on piano.
If a note is sharp or flat, that sign is after the number symbol. I thought this was really illiterate as a newbie to Nashville until I realized that it wasn't an analysis (b7, etc.) but the pitch name (7b would be Bb in the key of C). A minor chord is notated with a - after the chord, so Dm in the key of C would be 2-.
Nashville Number Charts make it very easy to change the key in which a song is to played. For instance, for the first take of a session, you might play a song in C. If that key is too high for the artist, the second take might be in Bb. If you're using a Nashville Number Chart, there's no need to transpose in your head or rewrite the chart. Here's an example:
In Nashville Number parlance a 12 bar blues would look like this:
1 1 1 1
4 4 1 1
5 4 1 5
Each number represents one measure. Thus, if you're in C (1=C, 4=F, 5=G) the progression is:
C C C C
F F C C
G F C G
If you're in Bb the Progression is:
Bb Bb Bb Bb
Eb Eb Bb Bb
F Eb Bb F
Here's another number progression. I've included a playalong in a Blues Style in G and Eb. See if you can compose a bass part and follow the number chart below. Good luck and have fun!
