Let's take the notes of the A major scale:
Now to make an A major chord, you just scoop up the 1st, 3rd and 5th notes, take your A-C#-E triad and punch your ticket on the A-Train to Chordtown. But if your guitar playing calls for an extra touch of class, toss in that 7th note, G#, and let your artistry soar.
1 2 3 4 5 6 7
A B C# D E F# G#
If you aren't intimately familiar with the 7th note in every major scale, it's a lot easier to count backwards than forwards. Since the 7th note is always only just a half-step away from the root, just think of sliding one semi-tone backward to find that major 7th note. For example, if you wanted to turn an F major into an F major 7, just think of the note directly preceding F, which is an E, and find a way to put that into your chord or lick.
