Hi, I am Ali Barouti a beginner guitar player, I’ve discovered something interesting which I want to share with you, I hope it be useful for everyone who is just started learning guitar.
There are several ways to learn the notes on guitar and every teacher believes knowing the notes helps learning to play the guitar. It helps you learn the scales and when you learned one transpose the scale boxes and learn the other scales much faster.
Well there are several ways and all those ways include memorizing.
Memorizing 3 string, memorizing one or two notes across the finger board and … I have seen in different websites and many forums people looking for a faster way to do this.
I myself was doing the same and while thinking about this I discovered a really interesting way to know all the notes on the guitar with a simple formula!
All right let’s do it
First of all each note has a number which I’ll explain why later
C(Do): 1 D(Re):3 E(Mi):5 F(Fa): 6 G(Sol): 8
A(La): 10 B(Si):12
Maybe you already know why E=5, every Notes except E-F and B-C has 2 Fret interval so:
C – D – E F – G – A – B C OR looking this way:
C C# D D# E F F# G G# A A# B (1,2,3,…,12)
You can see this very clearly at the second string which starts with Fret#1 = C
Thus for every open string you’ll have a number:
S1 (E) = 5 S2 (B) = 12 S3 (G) = 8 S4 (D) = 3 S5 (A) = 10 S6 (E) = 5
And every Fret will have a number: Fret Number + open String Number
Now if you want to find the 3rd fret of first string: 3 + 5 = 8 : its G ( 3rd Fret + 1st string’s number )
When the sum of these numbers are more than 12 first you subtract 12 until it’s less than 12 then look it up for example:
The 8th Fret of 3rd string: 8 + 8 = 16 16 – 12 = 4 its D#
For the second string because its open string number is 12 you won’t add 12 and then subtract it, simply the fret number is your note number: 2nd string 8th fret : 8 is G
Now even if you change your guitar tuning system this formula still works because the only thing changes are the open string’s numbers.
When you practice it in your mind a little you’ll find it’s too simple when you get familiar with.
S1 / F7: 7 + 5 =12 > B
S5 / F10: 10 +10 = 20 - 12 = 8 > G
S3 / F6: 6 + 8 = 14 – 12 = 2 > C#
S2 / F5: 5 + 0 > E
S4 / F18: 18 + 3 = 21 – 12 = 9 > G#
You know the fantastic part? The same Formula Applies for every instrument with strings and finger board!
