I play guitar and know it very well just not much theory. I know a C chord has the notes C, E and G. How would you figure out what a C7 without the notes being presented?

for example you know that a C Major is form by tonic, major third, and perfect fifth.


so C Major = C E G.

Now a C7 chord aka C dominant = you need a root, major third, perfect fifth, minor seventh


knowing the interval chart, also help u alot in finding the notes.


Root Note
Minor 2 - one half step up the root
major 2 - two half steps up the root
minor 3
major 3
perfect 4
Tritone aka aug 4/ dim 5
perfect 5
minor 6
major 6
minor 7
major 7
octave.


another way, is training your ear to recognize intervals.

so for example you ear this interval




E
B
G
D 5
A 3
E

You would know, that the sound belongs to a perfect fifth, you know you root "C" and what a perfect fifth up C, G!

The more deeper you unlock your ear, the more you will automaticly recognize "chords, intervals, scales" and their notes.

C1 D2 E3 F4 G5 A6 B7 C8

From this scale to get a 7th chord choose notes

1 -3 - 5 - 7

Apply to any scale or key, works the same!

Usually the notation C7 is used in respect to a C dominant 7 chord rather than C major 7 chord. The formula above is more often encountered under the name CM7 while de C7 has the following formula: 1 3 5 b7. I've seen both being used so, just pay attention to the context and you'll figure it out wink.gif
