Another chord that we see a lot in swing- and jump-blues is a 13th-chord.
As the names implies, it adds a 13th to the root of the dominant seventh formula 1-3-5-b7.
A 13th would be the same not as a 6th, one octave up.
A 6th can be found 9 frets (or 9 x 1/2 note) up from the root
Depending on the possibillities you have voicing the chord, the shapes you find can include the 9th too.
So a 13th chord could have the form 1-3-5-b7-13 or 1-3-5-b7-9-13.
Below is a C13 chord shape, one of the many that we can find.
This particular shape has the notes C, Bb, E and A.
Or stacked from bottom to top C, E, Bb, A: 1-3-b7-13.
Both the 9 and 5 are missing.
The reason for this is convenience.
Plus the chord is getting pretty thick with six notes in it.
Leaving the fifth out (in this case the G) doesn’t make that much difference to our ear.
If you don’t need it, dump it or let someone else play it.
