Where to learn Theory for beginners

You need the other 5 seventh chords - then you need to learn how all these chords can work together in real music.
That would help real music thata what its all about :D

need other 5 seventh chords do you mean in the other keys or which ones ?

The other 5 seventh chords built on the other 5 notes of the C scale after C and D. i.e., EFGA & B or chords iii7 IV7 V7 vi7 and vii7
Chord I7 was CEGB = C maj7
Chord ii7 was DFAC = D min7, as you told me yourself
The notes and names of the others - iii7, IV7 V7 etc., That's what I meant.
Do you know of any place that give a list of every chord in every key that i could get ?

Now that you're learning to do it yourself, that's the LAST thing you need. If you need to check how a particular chord is made, use Misanthrope's chord tools

ok key of C
C Dm Em F G Am Bdim
I7 = CEGB C7
ii7 = DFAC Dm7
iii7 = EGBD Em7
IV = FACE F7
V =GBDF G7
vi =ACEG Am7
vii =BDFA Bdim7 mmm :D or :cry:

i dont see any of these chords on list in chord and transposition tool

ok key of C
C Dm Em F G Am Bdim
I7 = CEGB C7
ii7 = DFAC Dm7
iii7 = EGBD Em7
IV = FACE F7
V =GBDF G7
vi =ACEG Am7
vii =BDFA B7b5 mmm :D or :cry:

Not bad - All notes correct but there are mistakes in the chord names (exactly where I expected them :lol: )

I7 is C major 7, not C7. They're not the same. The gap between the root note and the seventh is important. It can be 11 semitones (called a major 7th interval) or it can be 10 semitones (called a minor 7th interval).

Major chord + a note a major 7th interval higher = Major 7th chord
Major chord + a note a minor 7th interval higher = 7th chord
Minor chord + a note a minor 7th interval higher = Minor 7th chord

IV7 is F maj7 (same reason - F to E is 11 semitones, not 10)
and vii7 is B minor7b5 also called B half diminished seventh

do you know i had that in there because it was in the chord and transposition tool under B There is only to chords under B but i edit it and changed it blast but the major i was wrong WHY look

Because Dm is not D.

A letter used by itself indicates a major chord, and Dm is a minor chord.

You've completely lost me there, Frank. I don't see the connection.

Edit - Ah Ok - I see what you mean. Yes - By itself a letter means it's a major chord - so C major seventh, really means C major - major 7th. That's how I knew where to expect your mistakes.

my turn now im lost fretsorce said I7 is C major 7, not C7. They're not the same i thought they are the same so
C major seventh, really means C major - major 7th lost can i call it C7 if not why ?

oh like you now i think i see its a major 7th not the C your writing it for like C - major 7th ?

so why not call it C7TH IF C = C major

C7 is a Dominant 7th, C E G A#

CM7 is a Major 7th, C E G B

Cm7 is a Minor 7th, C E G A

(there are more too, but get your head around these first :wink:)

The dominant 7th is the one we're all used to seeing in tab as it's more common in western music but, as you've discovered, it contains a note that's out of key. The major seventh is in key, but because it has a note that is only one fret away from the root note (B and C in CM7), it can sound more dissonant than the dominant 7th.

It's the 'trick question' of diatonic chords :)

As for naming, the confusion arises because the chord can have major in its name, but the 7th note added to that 'base chord' can also. The dash Fretsource puts in the name is to seperate the name of the base chord from the name of the 7th note, ie:

C7's full name is C Major - Dominant 7th
Cm7's full name is C Minor - Dominant 7th
CM7's full name is C Major - Major 7th

And here's another table:

is this right the cords in the key

does having a # or a b in the chord change the name like CEG IS C what about D F#A IS D ?

just noticed A and B keys are very simular

LOL You have loads of these tables hbriem cool

No, those chords are not correct.
C Dm Em F G Am Bdim 7ths CMAJ7 Dm7 Em7 Fmaj7 Gmaj7 Am7 B7b5

That's almost correct except that the G is a G7, not a Gmaj7. The V chord is always a "7" chord (dom7), not a maj7. You've made the same mistake in all keys.

This is important because it is essentially the V7 that defines the key, at least to the ear.

A G7 has the notes G-B-D-F. A Gmaj7 would have G-B-D-F#.
D Em Fm G A Bm Cdim 7ths Dmaj7 Em7 Fm7 Gmaj7 Amaj7 Bm7 C7b5

The chords in D major are:

D Em F#m G A Bm C#dim
Dmaj7 Em7 F#m7 Gmaj7 A7 Bm7 C#7b5

D major has 2 sharps, F# and C#.
E Fm Gm A B Cm Ddim 7ths Emaj7 Fm7 Gm7 Amaj7 Bmaj7 Cm7 D7b5

E major has the chords:

I hope this helps.

What was i dong wrong ?

What was i dong wrong ?

You called chord V7, a major seventh chord in every key, when it's only a seventh chord (AKA dominant seventh).

In the key of C (CDEFGAB) V7 will be notes G + B + D + F.
If you count the frets (semitones) from G to F, you'll find it has only 10 - so it's a plain old seventh, not a 'major seventh' which has 11

What was i dong wrong ?

You were building the chords in each of the keys from the C major scale, not their own scale.

Let's take an example, E major, which is medium complicated ( 3 sharps (#).

If you look in the table I posted earlier, it has the notes:
Key Minor Signature 1 2 3 4 5 6 7
E major C# minor #### E F# G# A B C# D#

In steps this is just like C, but with different notes:
1_2_34_5_6_78
C_D_EF_G_A_BC
E_F#_G#A_B_C#_D#E

The underscores ( _ ) denote gaps. Thus the major scale has a half-step (semitone) between the 3 and 4 (EF) and between the 7 and 8 (BC). Whole steps (tones) between all the other notes.

This is sometimes written out:
WWHWWWH (in whole and half steps)
TTSTTTS (in tones and semitones)

All the major scales are built like this.

Now the chords are built from the notes of the scale, picking every other note.

Thus C major is C-E-G and E major is E-G#-B.
