When a dominant chord is played with a series of other chords like:
I, vi, ii , V7 in the key of C major: C maj //// Am //// Dm //// G7 ////
this is a functioning dominant seventh. Usually just for one measure or less.
The natural tension tones for G dominant seventh are: G7, G9, G11, G13.
G7  = R, 3, 5, b7           =  G, B, D, F
G9  = R, 3, 5, b7, 9       =  G, B, D, F, A 
G11 = R, 3, 5, b7, 9, 11, = G, B, D, F, A, C
G13 = R, 3, 5, b7, 9, 11, 13 = G, B, D, F, A, C, E 

When the dominant seventh is played for many measures it is non-functioning.
You can chose to use the natural tensions or altered tensions.
An altered tension means to sharp or flat the 5th or the 9th degree of the dominant chord.
G7b5  = R, 3, b5, b7              = G, B, Db, Bb
G7#5  = R, 3, #5, b7              = G, B, D#, Bb
G9b5  = R, 3, b5, b7, 9          = G, B, Db, Bb, A
G9#5  = R, 3, #5, b7, 9          = G, B, D#, Bb, A
G11b5 = R, 3, b5, b7, 9, 11    = G, B, Db, Bb, A, C
G11#5 = R, 3, #5, b7, 9, 11    = G, B, D#, Bb, A, C
G13b5 = R, 3, b5, b7, 9,11,13 = G, B, Db, Bb, A, C, E
G13#5 = R, 3, #5, b7, 9,11,13 = G, B, D#, Bb, A, C, E

G7b9  =  R, 3, 5, b7, b9
G7#9  =  R, 3, 5, b7, #9
G11b9 = R, 3, 5, b7, b9,11
G11#9 = R, 3, 5, b7, #9, 11
G13b9  = R, 3, 5, b7, b9,11,13
G13#9  = R, 3, 5, b7, #9, 11,13

Assignment record the following progressions then substitute functioning and non-functioning dominate seventh chords.

Original =     C maj //// Am //// Dm //// G7 ////
Substitute =  C maj //// Am //// Dm //// G9 ////

Original =     C maj //// Em //// F maj //// G7 ////
Substitute =  C maj //// Em //// F maj //// G7b5 ////

Original =     Dm //// G7 //// C maj //// Am7 ////
Substitute =  Dm //// G9#5 //// C maj //// Am9 ////
You can also use any diatonic substations from the family of chords (see archives - Diatonic Substitutions - Part 1 and 2). I used this here by replacing the A minor seventh with a A minor ninth.

Original =     Em //// Am //// Dm //// G7 //// C maj 7 ////
Substitute = Em //// Am //// Dm //// G13 // G7#5 // C maj 9 ////

Original =     F maj //// G maj //// Am //// G maj //// F maj //// G maj //// Am ////
Substitute = F maj //// G maj/9 //// Am //// G9#5 //// F maj7 //// G7 //// C/G ////
Also you can use the slash chords see: Slash Chords (five lessons previous).



Now transpose these to each position (register) of your instrument, then to all 15 keys.
