How does a 6th chord sounds like

Very important chords too. Made by a voice being 6 scale steps above bass. The 3rd is added. [Bach, Niedt]


Examples:


G bass and G B E or B E B etc


F bass and F A D


C#bass and A E A


It sounds great progressing for example from:


A C E ie A to
G B E ie G6 to
F A E ie F7
Note 6th, 7th are prepared for the listener's brain


Example:


Tell Him - Dion, Streisand
https://m.youtube.com/watch?v=X4p_3scB_8c#fauxfullscreen
at 0:14 bass is G and guitar plays E
both G and E are flat since key is A flat minor
This does not make a difference as everything in music is referenced in notation to white or natural keys
However the A flat key gives an ethereal character


Other example:


Qui Tollis, Mass in B minor - Bach
The first chord:
D bass and B D F
F is sharp since key is B minor


A sixth chord or harmony can also be thought as playing a minor chord but changing the bass to the second note of the harmonic triad.


For example:


Instead of playing B bass and B D F# playing
                              D bass and B D F# as on Bach's Masterpiece


Bach then uses prepared 7ths, 9ths on Qui Tollis
