Behind the Scenes! The Secret to Playing Thirteenths (in the key of C)

[youtube=http://www.youtube.com/watch?v=F84wl90L_us]

(Behind the Scenes Peek!  This is from Lesson 6 of AP 201 and is usually reserved for STUDENTS only)

There are several different ways to play thirteenth chords.  One way is to simply play the 11 chord (the chord a whole step down from the root note) and then add the 13th note.

Example: G11 = F A C  – Now add the 13th (E)   G13 = F A C E

The formal way to make a 13th chord is to take the b7, 9th, and 11th, and 13th of the major scale.

Example:

G A B C D E F# G A B C D E
1 2 3 4 5 6 7 8 9 10 11 12 13

The b7 = F; the 9th = A; the 11th = C, and the 13th = E.  Therefore a G13 = F – A – C – E over G in LH.

Exercise Song 1: Thirteenths on the I, IV and V Chords (b7, 9, 11, 13)

C  /  /  /  C13  /  /  /  F  /  /  /  F13  /  /  /

C  /  /  /  C13  /  /  /  G  /  /  /  G13  /  /  /   C

SONG 9: AMAZING GRACE

 C2   /  /          C13  /  /          Fmaj9  /    /          C    Bm11  E7#9   

Amazing        grace,      how sweet         the    sound,

         Am9  /  /      D9  /  /          Dm9  /  /   G9  /  G13

That saved   a    wretch      like    me,

    C2  /  /     C13   /  /     Fmaj9 /    /         C  Bm11   E7#9   

I once was    lost,     but  now       I’m   found,

          Am9  /  /   D9        /   G7b9        —  To Repeat: C2  /  /  F/G  /  /   C2

Was   blind but       now               I            see.

For a really fancy ending try this – To End: Ab2  /  /   Bb2 /  /  C2  

            But now I see.     

*Notice the b6 chord to the b7 chord ending at the end of the song, gives it a nice unique touch.  You can use this at the ending of any song to give it a cool ending; however, do not try and use it at the ending of every song.  Don’t overuse it!!

 

SUBSTITUTING THIRTEENTH CHORDS

There is only one rule for substituting thirteenth chords.

Anytime there is an eleventh chord, you can substitute a thirteenth chord.

NOTE: This rule does NOT apply to minor elevenths.

Thirteenth chords are very simple to substitute in songs.  They are usually used on the I to IV progression and on the V to I progression.

For example:

F  /  /  /       F  /  /  /    Bb  /  /  /   F  /  /  /

Dm  /  /  /  Gm  /  /  /  C /  /  /    C  /   /  /  F

Now let’s add some 13ths.

F2  /  /  /      F13  /  /  /    Bbmaj9  /  /  /   F  /  /  /

Dm9  /  /  /  Gm9  /  /  /   C2 /  /  /           C13  /   /   /  F2
