X7b13 and A7b5... help please....

[Ultraviolet]

Hi

trying to get me head around these...

could someone confirm the notes to play:

A7b5 = A C Eb G

D7b13 = D FSharp A C

E7b13 = E A B D

A7b13 = A CSharp DSharp FSharp

no idea if this is right or not, should it be root, 4th, sixth, ninth?

can someone help me out?

cheers,

A7b5 = A C# Eb G

D7b13 = D FSharp A C E G Bb

E7b13 = E G# B D F# A C

A7b13 = A C# E G B D F

In practice some of these notes would be left out. The b13 chords have 7 notes and that's a little tough for guitars. What notes to leave out is a matter of personal taste and musical need, but the fifth is usually the first one left out (unless it is flatted). The 11th is another that it usually left out in the case of the b13 chords. Using the 11th gives the chord a bit of a suspended sound(the 11th is the same note as the fourth, and it will clash with the third of the chord).

Good luck. Many of these kind of chord questions get easier when you really know all the major and minor scales.

The 11th is typically omitted from major quality chords because it creates a minor 9th interval in an inner voice and sounds like dookie, but if the quality of the chord is minor then the 11th sounds good and you can go nuts.

thanks guys...

so is it advisable to play someparts of the chord arpeggio and some notes simultaneuosly? e.g pull out the triads and play the other notes arpeggio?

also, if the chord is way outside of the key, should you include the note of the key somewhere?

First question...a matter of taste and totally dependent on the situation.

Second question...also a matter of taste and totally dependent on the situation.

I will say that trying to include too much info in a bassline can totally kill a tune. OTOH, you want to be creative and use some of the notes, so be judicious about it and use your ears.

Using a full arpeggio 1,3,5,7,9,(appropriate 11), 13 is nice way to move up the neck to go into a break for get into a solo. Using the upper extensions of chords is something that takes quite a bit of experience to make work.

Chords always relate to something could be a chord sub or key change though could be temporary key change or part of cycle of key changes as many Jazz tunes do. If on the bandstand and running into chord your not sure how its functioning using an arpeggio is your safety net.
